propyl pentanoate
pentyl propanoate
butyl propanoate
propyl butanoate
Correct answer is A
The alkyl group is attached to the parent chain being a carboxylic acid. The name of the compound is gotten by writing the name of the attached alkyl group first and then the parent carboxylic acid is written but you change the -oic acid to -oate.
The alkyl group in this case is \(C_{3}H_{7}\)
The parent carboxylic acid is \(C_{4}H_{9}COOH\) which is pentanoic acid.
Hence, the name is propyl pentanoate.
