Question

Assertion (A) Aryl halides undergo nucleophilic substitution with ease.
Reason (R) Hybridisation of $C$-atom attached to halide is $s{p}^3$-hybrid.

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

Answer 1

Answer: (D)

Both (A) and (R) are false as, aryl halides undergo nucleophilic substitution with great difficulty due to partial double bond character between $C$-atom of ring and halide atom. Also, hybridisation of $C$-atom attached to halogen is $s{p}^2$-hybrid.
