Chlorobenzene can be converted into phenol by heating in aqueous sodium hydroxide solution at temperature of 623K and a pressure of 300atm. However the rate of reaction can be increased by presence of certain groups in benzene ring. What will be the order of reactivity of following compounds towards the above substitution reaction?

A

(iii)gt(ii)gt(i)

B

(ii)gt(iii)gt(i)

C

(i)gt(ii)gt(iii)

D

(i0gt(iii)gt(ii)

Text Solution

Verified by Experts

The correct Answer is:
