Assertion : Acid catalysed hydrolysis of ester is reversible on the other hand base catalysed hydrolysis is irreversible. Reason : In acid catalysed ester hydrolysis carboxylic acid is formed on which nucleophile attack of alcohol is possible while in base catalysed ester hydrolysis carboxylate anion is formed on which nucleophillic attack is not possible.
A.A✓ Correct
B.B
C.C
D.D
Explanation
The acid catalyzed hydrolysis of ester is a reversible process and the base catalyzed reactions are irreversible process due to the nucleophilic attack of alcohol on acid which is not possible on base. Hence the correct answer is option (a) Intramolecular hydrogen -bonding Intermolecular hydrogen-bonding O H O C OH
