Carboxylic Acid Formulas

Carboxylic acids are nothing but organic compounds in which the carbon atom is bonded with an oxygen atom in the form of a double bond. The carbon atom can also be bonded to a hydroxyl group (−OH) by a single bond. There is also a fourth bond that exists and it links the carbon atom to a hydrogen atom or to some other univalent combining group. Carboxylic acid generally consist of on carboxyl group. Carboxylic acids with two or more carboxyl groups attached are called dicarboxylic acids, tricarboxylic acids, etc. The general molecular formula for carboxylic acid is Cn H 2 n+1 COOH .
