(a) Carboxylic acids are categorized as dicarboxylic acids, tricarboxylic acids and monocarboxylic acids etc. depending upon the number of - COOH groups available in the molecule.
(b) Monocarboxylic acids of aliphatic series are generally termed as fatty acids like palmitic acid (C15H31COOH) and stearic acid C17H35COOH.
(c) The general formula for monocarboxylic acids is Cnh2n+1COOH or CnH2nCOOH. In which n = number of carbon atoms.
(d) The carboxylic acids might be aliphatic or aromatic depending on if - COOH group is attached to aliphatic alkyl chain or aryl group correspondingly.
