CARBOXYLIC ACID Introduction: Organic compounds containing (–C(O)–OH) as a functional group are called carboxylic acids. The –C (O)-OH group which itself is made up of a carbonyl group (>C=O) and a hydroxyl group (-OH) is called a carboxyl group (carb from carbonyl and oxyl from hydroxyl group). Carboxylic acid may be an aliphatic or an aromatic depending upon whether –C–OH is attached to an alkyl group ( or a hydrogen atom) or an aryl group. Their general formulas are; ALIPHATIC CARBOXYLIC ACID: R–C
