Question

Assertion: Aryl halides undergo electrophilic substitution more readily than benzene.
Reason: Aryl halide gives a mixture of $o-,p-$ products when they undergo electrophilic substitution.

• A. Assertion and Reason are correct and Reason is the correct explanation of Assertion
• B. Assertion and Reason are correct but Reason is not the correct explanation of Assertion
• C. Assertion is true and Reason is false
• D. Assertion is false and Reason is true

Answer 1

The correct option is D Assertion is false and Reason is true

$X$- (halogen group)has two effects$-I$ & $+M$.
Due to $-I$ effect of $X$- group, it reduces electron density of benzene so halobenzene is less reactive than benzene for electrophilic substitution reaction.
But due to $+M$ effect, it is ortho, para directing and in halobenzene further substitution takes place at ortho and para positions.
