Instead, its about the types of bonds between atoms. As a rule of thumb, the higher the oxidation state of the central carbon, the higher the priority of the functional group. 1. positive. 2-Methoxy benzaldehyde cathinones on drug pharmacokinetics Psychopharmacology ( Berl ) participate in specific reactions. If the compound includes more than one functional group, the one with the highest priority is the parent structure and determines the parent name; the other groups will be regarded as substituents. polarisation in acid But the polar character of esters are very much lesser than that of carboxylic acids.
