The compound 'A' with molecular formula $C_{2} H_{4} O_{2}$ is ethanoic acid (acetic acid). Upon heating with ethanol (ethyl alcohol) and concentrated sulphuric acid, ethyl ethanoate (ethyl acetate) is formed as the product. It is an ester with pleasant or fruity smell. The reaction is known as esterification reaction.

${CH}_{3} COOH + C_{2} H_{5} OH \to {CH}_{3} {COOC}_{2} H_{5} + H_{2} O$
