  • question_answer
    Aryl halide is less reactive than alkyi halide towards nucleophilic substitution

    A) because it is a less stable carbonium ion

    B) due to large \[CCl\] bond energy

    C) due to inductive effect

    D) because of resonance stabilisation and \[s{{p}^{2}}\]-hybridisation of C-attached to halide

    Correct Answer: D

    Solution :

    [d] In aryl halide, the C in which halide is attached is \[s{{p}^{2}}C\] and \[CX\] bond experiences partial double bond character because of resonance. Hence, it becomes difficult to perform nucleophilic substitution for aryl halide.
