What type of smell is generally found in the ester formed from ethanoic acid and ethanol?

Answer and explanation

Correct answer: Sweet fruity smell

The governing concept is esterification, in which ethanoic acid reacts with ethanol in the presence of concentrated sulfuric acid to form an ester, ethyl ethanoate, and water: CH3COOH + C2H5OH → CH3COOC2H5 + H2O. Esters commonly have pleasant, sweet or fruity odours, and ethyl ethanoate is associated with a fruity smell. Thus option A is correct; the other smells are not characteristic of this ester.
