Question

Given below are two statements labelled as Assertion (A) and Reason (R).
Assertion (A) : –Cl is an o, p-directing group.
Reason (R) : –Cl activates the ring, towards electrophilic substitution reaction.
[0.77 Mark]

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is C A is true but R is false

–Cl directs the incoming electrophile at the o- and p-position because of its + M effects.
But its – $I_{\text{effect}}$ is more dominating because of which it deactivates the ring towards electrophilic substitution reaction.
