What is the correct IUPAC name for the following compound?
Options
- Aethyl 4-ketonepentanoate
- Bethyl 4-oxopentanoate
- Cethyl 4-ketone pentyl ester
- Dethyl ester methyl ketone
Correct answer
B. ethyl 4-oxopentanoate
Step-by-step solution
The given compound contains two functional groups: an ester and a ketone. According to IUPAC nomenclature rules, the ester group has higher priority than the ketone group. Therefore, the principal functional group is the ester, and the suffix of the parent chain will be '-oate'. The alkyl group attached to the oxygen atom of the ester is an ethyl group ( -CH₂CH₃ ). Numbering of the principal carbon chain starts from the carbonyl carbon of the ester group to give it the lowest possible locant (number 1). C1: Ester c
