Abstract:

We discuss in detail the meaning of "parent hydride" and "characteristic group", two terms used in organic chemistry. Through numerous examples, we demonstrate that nomenclature based on parent hydrides is superior in terms of convenience, systematization, and clarity. We also propose that "characteristic group" is a more accurate term than the commonly used "functional group" because each atom can only be described once.

Key words: Nomenclature of organic compounds, Parent hydride, Characteristic group, CCS-2017 rules
