The acidic hydrolysis of ether (X) shown below is fastest when
Text Solution
Verified by ExpertsThe correct answer is:
C
Ph 3 C–OR 
Ph 3 C–OH + ROH
The reaction proceeds by S N 1 Mechanism :
Ph 3 C–OR + H ⊕ 
Ph 3 C 
Ph 3 C ⊕ + ROH
Ph 3 C–OH 
Ph 3 C– 
Greater the electron releasing effect of the attached groups greater is the stability of intermediate carbocation, & faster is the rate of reaction.
If two ph– groups are replaced by 
groups, strong +M effect of MeO– groups stabilize, the carbocation better there by making the reaction faster.
