As we learnt in

Esterification of carboxylic acid -

⇒ Carboxylic acid with alcohols or phenols forms esters in the presence of catalyst H2SO4 / HCl

⇒  It's a kind of nucleophilic acyl substitution.

⇒  Involves cleavage of C - OH bond.

- wherein

RCOOH+R'OH\rightleftharpoons RCOOR'+H_{2}O

 

 Fruity smell is due to ester formation which is formed between ethanol and acid.

CH_{3}COOH+C_{2}H_{5}OH\overset{conc. \: H_{2}SO_{4}}{\rightarrow}CH_{3}COOC_{2}H_{5}+H_{2}O
