Question

The increasing order of hydrolysis of the following compounds is

• A. (i) < (iii) < (ii) < (iv)
• B. (i) < (iv) < (iii) < (ii)
• C. (iv) < (ii) < (iii) < (i)
• D. (i) < (iii) < (iv) < (ii)

Answer 1

Answer: (D)

(i) < (iii) < (iv) < (ii)

Answer 2

Cyclic and tertiary halides undergo hydrolysis by $S_{N} 1$ 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
