Verified step by step guidance1
Identify the ester functional group in the structure, which is characterized by a carbonyl group (C=O) adjacent to an ether linkage (O-C).
Determine the alkyl group attached to the oxygen atom of the ester. In this structure, the group attached to the oxygen is an isopropyl group, which consists of a central carbon atom bonded to two methyl groups (CH3) and one hydrogen atom.
Identify the acyl group, which is the part of the ester derived from the carboxylic acid. This is the portion of the molecule that includes the carbonyl group and the carbon chain attached to it. In this case, the acyl group is butanoate, which consists of a four-carbon chain (butyl) with a carbonyl group at the end.
Combine the names of the alkyl and acyl groups to form the systematic name of the ester. The name is constructed by placing the alkyl group name first, followed by the acyl group name.
The systematic name of the ester is 'isopropyl butanoate', indicating the isopropyl group attached to the oxygen and the butanoate group derived from the carboxylic acid.
