Select the correct option based on statements below:
| Assertion (A): | Like the bromination of benzene, bromination of phenol is carried out in the presence of Lewis acid. |
| Reason (R): | Lewis acid polarizes the bromine molecule. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | (A) is false but (R) is true. |
Hint: Bromination of phenol did not carried out in the presence of lewis acid.
Explanation:
In the case of phenol, the polarisation of the bromine molecules takes place even in the absence of Lewis acid. It is due to the highly activating effect of the –OH group attached to the benzene ring.
The bromination of phenol is carried out in the absence of Lewis acid.
Hence, Assertion is false but Reason is true.
