About Classification of Organic Compounds

Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
