Document Summary
Organic compounds are arranged into classes according to the particular functional groups that they contain. Members of each class of compounds share common chemical and physical characteristics. The names of organic compounds are assigned according to the class of the compound as determined by the functional groups. Iupac guidelines on nomenclature of organic compounds. Although called trivial names are known for many organic compounds, they are used colloquially and where it is simplest. However, a systematic nomenclature system that chemists use has been adopted by the international union of pure and applied chemistry (iupac) and is internationally accepted as the standard. Under this system one name fits one structure, and each name identifies a structure unambiguously. A systematic name consists of three parts: A prefix: appears before the stem name, and indicates a substituent on the chain (a substituent may be regarded as a group replacing hydrogen in the parent alkane).
