Read the assertion and reason carefully to mark the correct option out of the options given below:
(a)If both assertion and reason are true and the reason is the correct explanation of the assertion.
(b)If both assertion and reason are true but reason is not the correct explanation of the assertion.
(c)If assertion is true but reason is false.
(d)If assertion is false but reason is true.
Assertion: Phenol is more reactive than benzene towards electrophilic substitution reaction.
Reason : In the case of phenol, the intermediate phenoxide is more resonance stabilized.

Reason : In the case of phenol, the intermediate phenoxide is more resonance stabilized.
The correct option is A A
O-H group in phenol strongly activates the aromatic ring towards electrophilic substitution reaction at ortho & para positions due to + M effect. Further resonance stabilization of intermediate phenoxide ion favours ortho & para substitution.
