The differences between "Nomenclature of Organic Compounds-2017" and "Nonmenclature of Organic Chemistry (1980)" issued by Chinese Chemical Society are described. The general principles and numbering methods for naming substituent groups commonly used in organic chemistry for undergraduates are analyzed and explained; the proper systematic names are recommended to benefit classroom teaching and academic communication. Moreover, the principles such as systemization, standardization, simplification, uniformization, and "looking afterward" are proposed. Some recommendations are further presented:1) numbering the carbon skeleton of the substituent without compulsory numbering rule always begins at the point of attachment; 2) only preserving a minority of trivial names (common names); 3) naming methanoyl (formyl)-analogue groups following the name of methanoyl.

Key words: Organic compounds, Nomenclature, Substituent group
