Question

Assertion : Bromination of phenol takes place even in the absence of Lewis acid.
Reason : In phenol, OH^- group attached to benzene ring has highly
deactivating​

Answer 1

Answer:phenol acts as a lewis base .so even in the absence of lewis acid bromination can be done

Explanation:

Because of the presence of -OH group phenol acts as a proton donor ...

Answer 2

Answer:

The correct option is (c) The Assertion is a correct statement but the Reason is an incorrect statement.

Explanation:

Assertion: Bromination of phenol takes place even in the absence of Lewis acid. This is correct because bromination of benzene takes place in the presence of Lewis acid ($FeBr^3$) which polarises the Bromine molecule. But in the case of phenol, the OH group attached to the benzene ring is highly activated which polarises the Bromine molecule in the absence of Lewis acid.

Reason: In phenol, the  $OH^-$ group attached to the benzene ring has highly deactivating​. This is Incorrect because the $OH^-$ group attached to the benzene ring is highly activated.
