. The Increasing order of hydrolysis of the following compounds is


the increasing order of hydrolysis

(d)   (i) < (iii) < (iv) < (ii)

Best Answer

Answer ||| d

Solution ||| Cyclic and tertiary halides undergo hydrolysis by SN1 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

the increasing order of hydrolysis

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
