In the IUPAC naming of cyclic ketones, how is the numbering of the carbon atoms determined, and what is the specific rule for naming cyclic ketones?

In the IUPAC naming of cyclic ketones, numbering of carbon atoms is determined to provide the lowest possible locant for the carbonyl group. The carbonyl carbon is assigned the lowest possible number. The specific rule for naming cyclic ketones is to use the prefix “cyclo-” followed by the root alkane name for the carbon ring. The carbon atoms are numbered sequentially, starting with the carbonyl carbon as carbon-1. The position of the carbonyl group is then indicated by a numerical locant. This systematic approach ensures clarity and consistency in naming cyclic ketones, helping convey their structural information accurately.
