Electophilic substitution in phenol gene...

Electophilic substitution in phenol generally occurs at

A

`o-` and `p-` positions

B

`m-` position

C

only `o-` position

D

only `o-` position

Text Solution

Verified by Experts

The correct Answer is:
A
The `-OH` group bonded to the benzene ring directs the incoming electorphilic group to ortho and para positions in the ring as these positions become electron rich due to the resonance effective caused by `-OH` group.
