(a)
Interpretation:
The given ketone has to be named using
Concept Introduction:
For naming a ketone in IUPAC nomenclature, the suffix “-one” is added to the parent
IUPAC rules for naming a ketone:
The longest parent carbon chain is identified that includes the carbonyl group.
The parent chain name is changed by replacing the suffix “-e” with “-one”.
Numbering is done in a way that the carbonyl group gets the least numbering. The position of the carbonyl group is indicated in the name.
The identity and location of substituents if any has to be determined and this information has to be added in front of the IUPAC name.
Cyclic
ketones are named by adding the suffix “-one” to the name of the carbon ring. The substituents are numbered so that it gets the least numbering starting from the carbonyl group that is given the number 1.
