Detailed explanation-1: -Esters have a fruity smell because fruit gets their aromas from esters. The aroma of an ester is produced when alcohol combines with a carboxylic group (carbon bonded with oxygen atoms). Esters smell partly because they exhibit weak intermolecular forces.
Detailed explanation-2: –The intermolecular force of attraction between the esters is weak.-Due to this less intermolecular force of attraction the ester compounds are volatile in nature.-There is no existence of the hydrogen bond also in esters.-This volatile nature of esters makes us smell.
Detailed explanation-3: -Esters can help enhance flavor and are especially useful as an emulsifier. Emulsifiers are surfactants, meaning they reduce surface tension between two immiscible liquids, such as water and oil, thereby stabilizing the mixture.
