A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH).[1] The general formula of a carboxylic acid is R–COOH, with R referring to the alkyl group. Carboxylic acids occur widely. Important examples include the amino acids and acetic acid. Deprotonation of a carboxyl group gives a carboxylate anion.
