The increasing order of hydrolysis of the following compounds is

A) \[(i)\,<(iii)\,<(ii)\,<(iv)\]

B) \[N{{O}_{2}}\]

C) \[\pi \]

D) \[\pi \]

Correct Answer: D

Solution :

Cyclic and tertiary halides undergo hydrolysis by \[\therefore \] mechanism and involve the formation of carbocation intermediate. Greater the stability of carbocation intermediate, higher is the ease of halides to undergo hydrolysis. The order of  stability of carbocations is as               However, C ? Br bond in bromobenzene acquires some double bond character, hence it has least tendency to undergo hydrolysis. Therefore, the increasing order of hydrolysis of the given compounds is
