flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester the hydrogen in this group is replaced by a hydrocarbon group of some kind. This could be an alkyl group like methyl or ethyl‚ or one containing a benzene ring like phenyl[1]. Esters are widespread in nature
