Which of the following is most likely attacked by electrophile?

Correct Option - 2


Detailed Solution:

Order of reactivity towards electrophile

Strength of +M/+R : –OH > –CH₃ > –Cl

In case of halogens, their –I effect dominates over

+M hence –Cl is deactivating and  is lesser reactive than  for incoming electrophile.
