The IUPAC system employs the suffix -one added to the prefix identifying the longest carbon chain of \(RCOR'\) that includes the carbonyl group. The chain is numbered to give the carbonyl group. The chain is numbered to give the carbonyl group the lowest possible number. In the examples given, the names in parentheses correspond to a less systematic nomenclature of ketones by which the \(R\) groups each are named separately:
When the doubly bonded oxygen is regarded as a substituent along the parent chain or ring, it is called an oxo group, \(=O\),
