Directions : In this question, A statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as.
Assertion : In case of phenol, bromination takes place even in absence of Lewis acid whereas bromination of benzene takes place in presence of Lewis acid like FeBr3.
Reason : – OH group attached to benzene ring is highly deactivating.
Assertion : In case of phenol, bromination takes place even in absence of Lewis acid whereas bromination of benzene takes place in presence of Lewis acid like FeBr3.
Reason : – OH group attached to benzene ring is highly deactivating.
- a)If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
- b)If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
- c)If the Assertion is correct but Reason is incorrect.

Directions : In this question, A statement of Assertion (A) is followe...
Phenol contains an -OH group which activates the benzene ring towards electrophilic substitution.
Both the Assertion and Reason are correct, and the Reason correctly explains the Assertion.
Explanation:
In phenol, the presence of the -OH group activates the benzene ring towards electrophilic substitution. This is due to the electron-donating nature of the -OH group, which increases the electron density on the benzene ring, making it more susceptible to attack by electrophiles.
As a result, bromination can occur even in the absence of a Lewis acid catalyst. The electron density on the benzene ring is sufficient to attract and react with the electrophilic bromine.
On the other hand, in the case of benzene, the presence of a Lewis acid catalyst is required for bromination to occur. Benzene is not as electron-rich as phenol, and therefore needs a Lewis acid catalyst like FeBr3 to facilitate the reaction by generating a strong electrophile, FeBr4+.
Therefore, the Assertion is true, and the Reason correctly explains why bromination of phenol can occur in the absence of a Lewis acid, while bromination of benzene requires a Lewis acid catalyst.
Both the Assertion and Reason are correct, and the Reason correctly explains the Assertion.
