Explanation:

Esters are named as alkyl alkanoates. The general formula of an ester is \(R - COO - R'\). In the given compound \(CH_{3}-CH_{2}-C(=O)-O - CH_{2}-CH_{3}\), the part \(R'\) (the alkyl group attached to the oxygen) is \(CH_{2}-CH_{3}\) (ethyl group). The \(R - CO -\) part (\(CH_{3}-CH_{2}-CO -\)) is propanoyl (since it has 3 carbon atoms in the acyl group). According to IUPAC naming rules for esters, we name the alkyl group (\(R'\)) first and then the alkanoate (from the acyl part \(R - CO -\)).

Answer:

d) ethyl propanoate
