Carboxylic acids are organic acids characterized by the presence of a carboxyl group and are proton donors. Salts and anions of carboxylic acids are called carboxylates. The simplest series of carboxylic acids are the alkanoic acids, R-COOH, where R is a hydrogen or an alkyl group. Compounds may also have two or more carboxylic acid groups per molecule.
