prefix for 9 in chemistry

CH Chemistry Chp 9 Chemical Names and Formulas PowerPoint. September 2, 2022 by Alexander Johnson A prefix to the name comes before the molecule. See, They occur in words in the same languages as the original number word, and their respective derivatives. Multiple double bonds take the form -diene, -triene, etc., with the size prefix of the chain taking an extra "a": CH2=CHCH=CH2 is buta-1,3-diene. division by a multiple of 10 rather than multiplication by it. The anesthetic halothane (CF3CHBrCl) is 2-bromo-2-chloro-1,1,1-trifluoroethane. The prefix "D" comes from the Latin word dexter. A familiar example is cm, the centimetre symbol. Metric Prefixes for SI Units . StudyStack. The suffix is -ane if all of the carbon-carbon bonds are single bonds (formula CnH2n+2), -ene if at least one carbon-carbon bond is a double bond (formula CnH2n), and -yne if there is at least one carbon-carbon triple bond (formula CnH2n-2). These compounds are neutral overall. Simply add the name of the attached halide to the end of the acyl group. Organic Chemistry Prefixes Halogen substituents are also indicated using prefixes, such as fluoro (F-), chloro (Cl-), bromo (Br-), and iodo (I-). Values of quantities are expressed using Arabic symbols for numbers paired with a unit symbol, often with a prefix symbol that modifies unit magnitude. Also, very long names may be less clear than structural formulas. Some simple examples, named both ways, are shown in the figure above. Prefixed substituents are ordered alphabetically (excluding any modifiers such as di-, tri-, etc. The N position indicator for amines and amides comes before "1", e.g., CH3CH(CH3)CH2NH(CH3) is N,2-dimethylpropanamine. Alternatively, the suffix "-carboxylic acid" can be used, combined with a multiplying prefix if necessary mellitic acid is benzenehexacarboxylic acid, for example. Four prefixes were added. Numbers are used to identify the position of the substituent. Simple cis and trans isomers may be indicated with a prefixed cis- or trans-: cis-but-2-ene, trans-but-2-ene. Section 9.1 Naming Ions OBJECTIVES: -Identify the charges on monatomic ions by using the periodic table, and name the ions. Was this answer helpful? Sci Chp3 Basic Chem. A benefit of the SI (International System of Units) is that written technical information is effectively communicated, transcending the variations of language including spelling and pronunciation. R-3.2.1.1 The presence of a characteristic group can be denoted by a prefix or suffix attached to the parent name (with elision of terminal "e", if present). . Prefix Progress. They are combined to create, 4,8-diethyl. The prefix "L" comes from the Latin word laevo. Because these elements have only one oxidation state, you dont need to specify anything with a prefix. (But this is not necessarily the final grouping, as functional groups may be added in between to ensure all groups are listed alphabetically.). Words containing non-technical numerical prefixes are usually not hyphenated. Straight-chain alkanes take the suffix "-ane" and are prefixed depending on the number of carbon atoms in the chain, following standard rules. They are modifiers on the root word that tell us the unit of measure. Organic Chemistry Prefixes CH Chapter 3 Section 3 6 Molecular Compounds Formulas. It means "on the right side". II. When you want to express some large or small quantities, you may also find these prefixes useful. 1. The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and undecane which has mixed-language prefixes. 3. Rachel Lynette. Some of the SI prefixes denote negative powers of 10, i.e. For example, CHCl3 (chloroform) is trichloromethane. The groups are on carbon atoms 3 and 9. The order of remaining functional groups is only needed for substituted benzene and hence is not mentioned here. You are planning an exercise that will include the m16 and m203. The root language of a numerical prefix need not be related to the root language of the word that it prefixes. Some examples of molecular compounds are water (H2O) and carbon dioxide (CO2). Thus, CH3CO2K can be named as potassium acetate or as potassium ethanoate. is called pentanenitrile or butyl cyanide. It is important that you do this as you will not be able to follow the science later on in the course if you do not understand the meanings of the terms used. Chemistry prefixes are used to denote the number of atoms of each element in a molecule. Branched alkanes are named as a straight-chain alkane with attached alkyl groups. NOTE: If you already know an answer you can just click "I got it right" and move on to the next. The di-, tri- etc. What are the disadvantages of shielding a thermometer? Simple cations formed by adding a hydron to a hydride of a halogen, chalcogen or pnictogen are named by adding the suffix "-onium" to the element's root: H4N+ is ammonium, H3O+ is oxonium, and H2F+ is fluoronium. The second system, the stock system, uses oxidation numbers to represent how the electrons are distributed through the compound. Several common-use numerical prefixes denote vulgar fractions. Put the two elements together, and dont forget the ide on the second element. It should have the maximum number of substituents or branches cited as prefixes. A challenge for you to think more deeply . The prefix of the molecule's name is based on the number of carbon atoms. On this Wikipedia the language links are at the top of the page across from the article title. Ionic compounds will follow set of rules, and molecular compounds will follow another. Check Eligibility. Because the SI prefixes strictly represent powers of 10, they should not be used to represent powers of 2. Department of Chemistry and Biochemistry Fayetteville, Arkansas 72701. Thus, because compound prefixes are unacceptable, symbols for decimal multiples and submultiples of the unit of mass are formed by attaching SI prefix symbols to g (gram). Acid anhydrides (R-CO-O-OC-R) have two acyl groups linked by an oxygen atom. SI Prefix symbols are featured in the chart and used to represent smaller or larger units by factors that are powers of 10. The convention of writing a zero before the decimal point is used to ensure that the quantity is appropriately interpreted. Thus CH3OCH(CH3)2 is 2-methoxypropane. Everytime you reload these should rearrange. Alkynes are named using the same system, with the suffix "-yne" indicating a triple bond: ethyne (acetylene), propyne (methylacetylene). Step 1: Explanation. The suffix or ending of the name of a hydrocarbon depends on the nature of the chemical bonds between the carbon atoms. haracteristics Distance Total . Also, the vowel at the end of a prefix is sometimes dropped when the name of the element begins with a vowel. When the main functional group is a terminal functional group (a group which can exist only at the end of a chain, like formyl and carboxyl groups), there is no need to number it. Once you have determined each prefix, you need to add the ide suffix if the second name in the compound is an element (this is sometimes not the case for more complex molecules). Four prefixes were added. "Milli" refers to 10 -3, while "nano" refers to 10 -9. The difference between these is 10 6, and since we are going down the table, the exponent should be positive. \[ \begin{align} 1,330,000,000m& =1.33\times 10^{9}m =1.33 \; gigameters\nonumber \\13,300,000,000m& =13.3 \times 10^{9}m=13.3 \;gigameters\nonumber\\ 133,000,000,000m& =133\times 10^{9}m = \; 133 \; gigameters\end{align}\]. Activity $\PageIndex{4}$: Abbreviation to Prefix. Amines (RNH2) are named for the attached alkane chain with the suffix "-amine" (e.g., CH3NH2 methanamine). Numbering of the chain. For the hundreds, there are competing forms: those in -gent-, from the original Latin, and those in -cent-, derived from centi-, etc. The ordinal series are based on ordinal numbers such as the English first, second, third (for numbers higher than 2, the ordinal forms are also used for fractions; only the fraction .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}12 has special forms). An official website of the United States government. Numerical prefixes are not restricted to denoting integers. (6.8k) $6.98. For example, (CH 3) 2 CHCH 2 CH 2 Br is named 1-bromo-3-methylbutane. Prefixes is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts. Prefix Symbol Meaning ; deci: d: 10-1 centi: c 10-2 milli: m 10-3 micro: For example, P 4 O 6 and P 4 O 10 are called phosphorus trioxide and phosphorus pentoxide respectively. For example, 10 3 would have the kilo prefix, 10 6 would have the mega prefix, and 10 9 would have the giga prefix . IUPAC NOMENCLATURE OF ORGANIC CHEMISTRY- YOUTUBE VIDEO LECTURE RULES. The -oate changes to -ate. The ENG key takes large or small numbers and expresses them as integer multiples of 103 or 10-3, effectively converting them to values that can be expressed with SI prefixes. The purpose of organic chemistry nomenclature is to indicate how many carbon atoms are in a chain, how the atoms are bonded together, and the identity and location of any functional groups in the molecule. ThoughtCo. For example, C6H5CO2Na, the sodium salt of benzoic acid (C6H5COOH), is called sodium benzoate. If you type 1,200,000 into your calculator and press ENG, it gives 1.2 x 106, so 1,200,000 bytes of memory on a memory stick would be 1.2 MBytes (you do not say 1,200 kBytes). The first three of the names shown above are still considered to be acceptable IUPAC names. Google Apps. Thus, one kilobit, or 1 kbit, is 1000 bit and not 2 10 bit = 1024 bit. This is essentially the roman numeral system that has already been explained, but it applies to non-ionic compounds as well. The following activities are drill and practice. Identification of the side-chains. Explanation: Greek prefixes are used for binary (two element) molecular compounds. If both acyl groups are the same, then the name of the carboxylic acid with the word acid is replaced with the word anhydride and the IUPAC name consists of two words. What are Rules for Prefix in a compound? plus the prefixes for 19. The side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. Eight original SI prefixes were officially adopted: deca, hecto, kilo, myria, deci, centi, milli, and myrio, derived from Greek and Latin numbers. The name of each substitution is prefixed to the hydride cation name.

For other uses, see, These months' prefixes originated with the early Roman 10-month calendar. In chemistry, a number of prefixes, suffixes and infixes are used to describe the type and position of the functional groups in the compound. The arrangement (with punctuation) is: 18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricosa-6,13-dien-19-yne-3,9-dione, This page was last edited on 7 February 2023, at 22:16. NIST SI Measurement System Chart (2021) is a colorful chart explaining the 7 base units of the SI, prefix symbols, and features the Measurement League: Guardians of the SI. For example, $\ce{P4O6}$ and $\ce{P4O10}$ are called phosphorus trioxide and phosphorus pentoxide respectively. Brief summary of contents of 'Complete course for students'. The common prefixes are given in this Table. When compounds contain more than one functional group, the order of precedence determines which groups are named with prefix or suffix forms. Systematic names and words comprising SI prefixes and binary prefixes are not hyphenated, by definition. If there are different groups, they are added in alphabetical order, separated by commas or hyphens. Other articles where prefix is discussed: steroid: Steroid numbering system and nomenclature: trivial nomenclature, a number of prefixes are often attached, with locants, to the names of steroids to indicate specific modifications of the structure. It is also commonly used in chemistry and other sciences. Understandably, the rules for naming organic compounds are a lot more complex than for normal, small molecules. The table is arranged in a symmetric fashion for convenience of comparison. Each alkane name is built from a prefix (first part) and a suffix (ending). If higher precedence functional groups are present (see order of precedence, below), the prefix "hydroxy" is used with the bonding position: CH3CHOHCOOH is 2-hydroxypropanoic acid. {\displaystyle {\ce {CH3CH2CH2CH2C#N}}} A molecular compound consists of molecules whose formula represent the actual number of atoms bonded together in that molecule. You can use the -replace operator. Lastly, you will be given different examples to practice with naming chem prefixes. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The IUPAC nomenclature also provides rules for naming ions. Prefixes for the powers of ten are grouped into sets of three zeros, with smaller increments near the number 1. Molecules use prefixes mono, di, tri, Prefixes for Naming Binary Molecules 1 mono 2 di 3 tri 4 tetra 5 penta 6 hexa 7 hepta 8 octa 9 nona 10 deca 11 undeca 12 dodeca Examples: IF 5 iodine pentafluoride N2O5 dinitrogen pentoxide CO carbon monoxide (ok to drop "mono" on first word) Naming Ions Ion Name: element name + ion Robert E. Belford (University of Arkansas Little Rock; Department of Chemistry). According to the current version of Nomenclature of Organic Chemistry - IUPAC Recommendations and Preferred Names 2013 (Blue Book), simple prefixes (simple substituent groups consisting of just one part that describes an atom, or group of atoms as a unit, for example methyl, cyclohexyl, and isopropyl) are arranged alphabetically disregarding any Some of the examples show the variations. What is A person who sells flower is called? Aldehydes (R-CHO) take the suffix "-al". Example: 1 mg, NOT 1 kg (1 microkilogram). Learn how to easily name ionic and covalent compounds. Cycloalkanes and aromatic compounds can be treated as the main parent chain of the compound, in which case the positions of substituents are numbered around the ring structure. NOTE: If you already know an answer you can just click "I got it right" and move on to the next. *Note: These suffixes, in which the carbon atom is counted as part of the preceding chain, are the most commonly used. The first step is to count the number of each element. $2.00. The distributive series originally meant one each, two each or one by one, two by two, etc., though that meaning is now frequently lost. Just sayin'. Identification of the remaining functional groups, if any, and naming them by their ionic prefixes (such as hydroxy for -OH, oxy for =O, oxyalkane for O-R, etc.). The following are not related, but are worth comparing: peri circum around syn/sym, etc. . Note also that some names are given using other conventions. With a little bit of practice, naming compounds will become easier and easier! Websters pronunciation guidance reflects contemporary American English. Answer (1 of 2): According to IUPAC, naming in organic chemistry (hydrocarbons) must be done in accordance of following; for 1 carbon - use 'meth' (single bond-methane) for 2 carbons - use 'eth' (single bond-ethane; double bond-ethene; triple bond-ethyne) for 3 carbons - use 'prop' (single bo. If more than one functional group is present, the one with. Given the prefix size, give its name: 11) 10 15 12) 1,000 13) 10 9 14) 10 2 15) 0.000001 Go to answers for 1-15 Solve any question of Some Basic Concepts of Chemistry with:-. The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. Organic Chemistry Prefixes and Suffixes. Helmenstine, Anne Marie, Ph.D. "Organic Chemistry Prefixes and Suffixes." Has the lowest-numbered locants for multiple bonds (The locant of a multiple bond is the number of the adjacent carbon with a lower number). As there are two, we write 3,9-dione. If the carbon in the carbonyl group cannot be included in the attached chain (for instance in the case of cyclic aldehydes), the prefix "formyl-" or the suffix "-carbaldehyde" is used: C6H11CHO is cyclohexanecarbaldehyde. Are you pronouncing 'kilometre' correctly. Chemistry Organic Chemistry Naming Alkanes, Alkenes, and Alkynes 1 Answer Meave60 Sep 13, 2017 Refer to the explanation. However, the common or trivial name is often substantially shorter and clearer, and so preferred. If a higher precedence suffix is in use, the prefix "oxo-" is used: CH3CH2CH2COCH2CHO is 3-oxohexanal. For example, H 2 C=O is named as per the IUPAC system as methanal, commonly known as formaldehyde. In Scientific Notation there is on digit to the left of the decimal, in Engineering notation there are 1, 2 or 3 digits to the left of the decimal, and you then use one of the Si prefixes that is of the magnitude 103n. Chemists need to be able to convert between different ways of expressing, but the first step is to memorize the unit definitions themselves. Introduction to Chemistry Prefixes Number of Atoms: Prefixes 1: mono 2: di 3: tri 4: tetra 5: penta 6: hexa 7: hepta 8: octa 9: nona 10: deca The above list shows the 10 most basic chemistry prefixes for naming compounds, which come from Greek. The pattern can be seen below. This pack includes 36 Prefix and Suffix task cards that would fit into any class activity, or as a center/station in your Literacy Block.Included:- Task Cards- Recording Sheets- Answer Keys and Suggestions- 2 Signs/PostersSimply print (back if you want), laminate, cut and organize to use in your cla. So the ENG function quickly converts numbers to values that can easily be expressed with SI prefixes. https://www.thoughtco.com/hydrocarbon-nomenclature-prefixes-608208 (accessed March 1, 2023). It is called tricosa-. The above cations except for methanium are not, strictly speaking, organic, since they do not contain carbon. In general, carboxylic acids are named with the suffix -oic acid (etymologically a back-formation from benzoic acid). What is the Denouement of the story a day in the country? The multiple series are based on adverbial numbers like the English once, twice, thrice. Find the longest continuous carbon chain a. Because it contains carbon-carbon double bonds, the -ene suffix is present. To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. 4.8. Naming Aldehydes. 5) Finally add prefix(es) to the IUPAC name, if there are side chains or substituents on the parent chain. Prefix Symbol Meaning ; deci: d: 10-1 centi: c 10-2 milli: m 10-3 micro: Legal. (di- after #,#, tri- after #,#,#, etc.). Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. Follow. In a later section you are going to have to learn how to convert between SI units, or even between SI units and scientific notation. For example: In many European languages there are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. Often, the symbols are used together with units. Tertiary amines (RNRR) are treated similarly: CH3CH2N(CH3)CH2CH2CH3 is N-ethyl-N-methylpropanamine. You will also learn the basics of these chemistry prefixes and how they are applicable in the real world today! Now, ronna (R) and ronto (r) will describe multiplying factors of 1027 and . For more information, see our tutorial on naming ionic compounds. Legal. Three for forming multiples: mega, giga, and tera. Use a leading zero for numbers less than one. Why were Mexican workers able to find jobs in the Southwest? ILTS Science - Chemistry (106): Test Practice and Study Guide In order to correctly convert one metric unit to another, you will need to determine which of two prefixes represents a bigger amount and then determine the exponential "distance" between them. Prefixes, Suffixes, and Roots are essential for vocabulary growth, and these worksheets are perfect to have students practice prefix, suffix, and root problems.WHAT'S INCLUDED: PRINT:40 WorksheetsAnswer KeysDIGITAL:120 Google Slides"Worksheet Style" Google SlidesSelf . "cyclohexyl-") or for benzene, "phenyl-". Scientific notation is a useful means to write out very large or very small numbers using powers of ten and exponents. The . We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. [B] There is also an international set of metric prefixes, which are used in the metric system and which for the most part are either distorted from the forms below or not based on actual number words. Improve this answer. If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH2COOH is 3-oxopropanoic acid. Several technical numerical prefixes are not derived from words for numbers. Similarly, some are only derived from words for numbers inasmuch as they are word play. What Is an Enzyme Structure and Function? Dont get frustrated with yourself if you dont understand it right away. CH If there are both double bonds and triple bonds, "en" (double bond) is written before "yne" (triple bond). The steps for naming an organic compound are: . . The prefix of the molecule's name is based on the number of carbon atoms. What does the prefix D mean in chemistry? For example, CH3COCl is ethanoyl chloride. So a memory stick with 1,200,000 bytes would be written as 1.2 Mbyte, not as 1,200 kbytes. A locked padlock For example, CH3COOOCCH3 is called ethanoic anhydride and CH3COOOCCH2CH3 is called ethanoic propanoic anhydride. Greek prefixes are often used for naming compounds. [citation needed]. Share. The IUPAC nomenclature scheme becomes rapidly more elaborate for more complex cyclic structures, with notation for compounds containing conjoined rings, and many common names such as phenol being accepted as base names for compounds derived from them. Examples: Subject, subtract, subjugate, subnitrate, suboxide, subchloride, subplot, subcommittee, subvert, submerge, submarine, subscribe, subtropical, etc. It can also be named by replacing the -oic acid of their corresponding carboxylic acids with -onitrile. There is chemistry all around us every day, even if we dont see it. The prefix form is both "carbamoyl-" and "amido-", e.g., HCONH2 methanamide, CH3CONH2 ethanamide. A word to the wise: deca- (symbol = da) is a little used unit prefix. Some examples of ionic compounds are sodium chloride (NaCl) and sodium hydroxide (NaOH). You need to memorize the red SI prefixes in table $\PageIndex{1}$. The root names of hydrocarbon molecules are based on whether they form a chain or ring. For example, we might think to call C2H6 dicarbon hexahydride, but in reality its called ethane. For example, the prefixdeka is used (American English spelling) but not deca (British English). For example, (CH3)2CHCH3, commonly known as isobutane, is treated as a propane chain with a methyl group bonded to the middle (2) carbon, and given the systematic name 2-methylpropane. Use prefixes appropriately to indicate the number of each kind of atom. The position of the hydroxyl group(s) on the parent chain is(are) indicated by placing the number(s) corresponding to the location(s) on the parent chain directly in front Ionic compounds have the simplest naming convention: nothing gets a prefix. The numbering of the molecule is based on the ketone groups. In this tutorial, you will be introduced to the different types of chemistry prefixes. Note that some of the prefixes may change slightly when they are applied to the names. Phone: 479.575.6499 This is not an absolute rule, however, and there are exceptions (for example: quarter-deck occurs in addition to quarterdeck). In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended[1][2] by the International Union of Pure and Applied Chemistry (IUPAC). . Activity$\PageIndex{3}$: Value to Prefix. The R-CO-O part is then named as a separate word based on the carboxylic acid name, with the ending changed from -oic acid to -oate. The smaller number is always used, not the sum of the constituents numbers. Again, the substituent groups are ordered alphabetically. You should contact him if you have any concerns. Citric acid serves as an example: it is formally named 2-hydroxypropane-1,2,3-tricarboxylic acid rather than 3-carboxy-3-hydroxypentanedioic acid. So we would say 16Gigabytes and not 16,000 Mbytes of 16,000,000 kbytes. Homework resources in SI Unit Prefixes - Chemistry - Science. Spelling. It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). If the acyl groups are different, then they are named in alphabetical order in the same way, with anhydride replacing acid and IUPAC name consists of three words. The breadth, depth and veracity of this work is the responsibility of Robert E. Belford, rebelford@ualr.edu. Some words comprising numerical prefixes are hybrid words. Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College, -ic acid indicates a carboxylic acid, which has the O=C-OH functional group. Everytime you reload these should rearrange. H5C+ is methanium, HO-(O+)-H2 is dioxidanium (HO-OH is dioxidane), and H2N-(N+)-H3 is diazanium (H2N-NH2 is diazane). Second element; named as if it were an anion (-ide suffix) always gets a prefix mono - 1 penta - 5 octa - 8 di - 2 hexa - 6 nona - 9 tri - 3 hepta - 7 deca - 10 tetra - 4 C. Naming Acids; Binary Acids (two elements - hydrogen + one other) a. prefix "Hydro" + root of second element + "ic" suffix . Capitalization. These prefixes can be used to name just about any compound. We have all heard of SI prefixes, for example you may have a 16 Gbyte flash drive, where the G stands for giga and means 109, and that is a much more convienent way of expressing the number of bytes than using the floating number of 16,000,000,000 bytes. Set your categories menu in Theme Settings -> Header -> Menu -> Mobile menu (categories), CO= carbon monoxide. The first General Conference on Weights and Measures (CGPM) approves the 8 prefixes for use. Since the first eight prefixes were adopted by the CGPM in 1889, there have been five subsequent prefix expansions. prefix only if there is more than one atom b. Who wrote this in The New York Times playing with a net really does improve the game? IUPAC Recommendations on Organic & Biochemical Nomenclature, Symbols, Terminology, etc. Therefore, HClO 4 is called perchloric acid. End the name of the second element with the suffix -ide. FAQ: How do I pronounce the prefix giga? Remember that this rule only applies to the first element of the two. The carbon skeleton is how many carbons are linked to each other. If an aldehyde is attached to a benzene and is the main functional group, the suffix becomes benzaldehyde. If there are multiple side-branches of the same size alkyl group, their positions are separated by commas and the group prefixed with di-, tri-, tetra-, etc., depending on the number of branches. For example,(CH3)2CHCH2CH2Br is named 1-bromo-3-methylbutane. 4) Prefix the root word with the infix "cyclo" if the parent chain is cyclic; or with the infix "spiro" if it is a spiro compound; or with the infix "bicyclo" if the compound is bicyclic.
