DefinitionThis section has been translated automatically.

Monocarboxylic acids are chemical compounds that have only one carboxyl group (-COOH) in the molecule. Compounds with several carboxyl groups are accordingly called di- or tricarboxylic acids.

Carboxylic acids are widespread in nature. Important monocarboxylic acids are acetic acid, propionic acid and butyric acid. Monocarboxylic acids also include the longer-chain fatty acids.

Monocarboxylic acids can be named according to the IUPAC nomenclature by appending the syllable "acid" to the name of the corresponding alkane. Aromatic monocarboxylic acids contain an aromatic ring structure in their molecule. Frequently, however, the (mono-) carboxylic acids are known by their trivial name.
