Methane, ethane, propane, n-butane, isobutane, and neopentane are common names. Many common names became so popular that they are still widely used by chemists. These names existed long before organic chemistry became an organized branch of chemical science and structure of organic compounds was not known. This is unscientific system in which certain (not all) compounds are named after their source, their property or a historical aspect.

Nomenclature of Organic Compounds There are two general ways for naming organic compounds, namely trivial name (common name) and IUPAC methane, ethane, methanol, methylamine etc.)īenzenoid (e.g. Open chain or Acyclic or Aliphatic compounds (e.g. Rules for Nomenclature of Alicyclic Compounds Nomenclature for Polycyclic Compounds Nomenclature of Aromatic CompoundsĬlassification of Organic Compounds All the known organic compounds have been divided into various classes as follows. Naming of Compounds having Functional Groups IUPAC Names of Some Organic Compounds Naming of Polyfunctional Compounds Containing Two or More Similar Carbon-Containing Terminal Groups Structural Formula from the IUPAC Name Classification of Organic Compounds Nomenclature of Organic CompoundsĪlkyl, Alkenyl and Alkynyl Groups Bond-Line Formulas Nomenclature of Branched Chain Alkanes
