Verified step by step guidance
1
Identify the functional group present in the compound. In this case, the compound contains a carbonyl group (C=O) adjacent to an oxygen atom bonded to another carbon chain, indicating it is an ester.
Determine the alkyl group attached to the oxygen atom. Here, the group attached to the oxygen is a two-carbon chain (ethyl group).
Identify the acyl group (the part of the ester derived from the carboxylic acid). The acyl group here is a four-carbon chain with a methyl group on the second carbon (2-methylbutanoyl group).
Combine the names of the alkyl and acyl groups to name the ester. The name is formed by placing the alkyl group name first, followed by the acyl group name with the suffix '-ate'.
The final name of the compound is ethyl 2-methylbutanoate.
