उत्तर
Both A and R are true but R is not the correct explanation of the Assertion.
Explanation:
Esterification is a process in which ethanoic acid reacts with absolute ethanol in the presence of an acid catalyst to give sweet-smelling substance called esters.
\[\ce{CH3COOH + CH3CH2OH->[acid] CH3COOCH2 CH3 + H2O}\]
In this question, both the assertion and reason are correct but, the reason is not the correct explanation of the assertion.
