The functional group present is an ester, which is characterized by a carbonyl group (C=O) bonded to an oxygen atom (O).
Step 2: Identify the alkyl groups attached to the ester
The alkyl groups attached to the ester are:
A methyl group (\(CH_3\)) attached to the carbonyl carbon.
A hexyl group (\(C_6H_{13}\)) attached to the oxygen atom.
Step 3: Name the ester
Esters are named by stating the alkyl group attached to the oxygen atom first, followed by the name of the carboxylic acid part. The carboxylic acid part's name is derived from the corresponding alkane, with the '-e' ending replaced by '-oate'. In this case, the alkyl group is hexyl, and the carboxylic acid part is derived from ethane (since there are two carbons attached to the carbonyl group). Thus, the name is hexyl ethanoate.
