Assertion : Chlorobenzene is more reactive than p-chloroanisole to nucleophilic substitution reaction. Reason : Greater the stability of carbanion, greater is its ease of formation and hence, more reactive is the aryl halide.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
On comparing the relative stabilities of carbanion of chlorobenzene and anisole. The electron donating group in anisole tends to intensify the negative charge relative to carbanion in chlorobenzene. Thus. pchloroanisole is less reactive than chlorobenzene. Hence option (1) is correct.

Assertion : Carbon-halogen bond in aryl halide has partial double bond character. Reason : Aryl halides undergo nucleophilic substitution easily.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Carbon-halogen bond in aryl halide has partial double bond character due to the hybridization of carbon atom. Aryl halides undergo nucleophilic substitution with difficulty. So option (3) is correct.

Match the reactions in column I with their reaction conditions given in column II and mark the appropriate choice.
1 A - P, B - Q, C - R
2 A - R, B - Q, C - P
3 A - R, B - P, C - Q
4 A - Q, B - P, C - R
Explanation:
The presence of EWG increases the NSR tendency on halo benzene. Thus, as the number of group increases at ortho and para positions, the reaction gets favourable even in normal conditions. So, the correct option is (1)
