Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Aryl halides cannot be prepared by replacement of hydroxyl group of phenol by halogen atom. Reason R : Phenols react with halogen acids violently. In the light of the above statements, choose the most appropriate from the options given below. (1) A is false but R is true (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) Both A and R are true and R is the correct explanation of A

1. A is false but R is true
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. Both A and R are true and R is the correct explanation of A

Correct answer: A is true but R is false

Solution

Assertion A is true because aryl halides cannot be formed by simply replacing the hydroxyl group in phenol due to the stability of the phenolic structure. Reason R is false as phenols do not react violently with halogen acids; instead, they typically undergo electrophilic substitution reactions.
