  • question_answer
    In \[{{S}_{N}}2\]reactions, the correct order of reactivity for the following compounds : \[C{{H}_{3}}Cl,C{{H}_{3}}C{{H}_{2}}Cl,{{(C{{H}_{3}})}_{2}}CHCl\]and\[{{(C{{H}_{3}})}_{3}}CCl\]is:   JEE Main  Solved  Paper-2014

    A) \[C{{H}_{3}}C{{H}_{2}}Cl>C{{H}_{3}}Cl>{{(C{{H}_{3}})}_{2}}CHCl>{{(C{{H}_{3}})}_{3}}CCl\]

    B) \[{{(C{{H}_{3}})}_{2}}CHCl>C{{H}_{3}}C{{H}_{2}}Cl>C{{H}_{3}}Cl>{{(C{{H}_{3}})}_{3}}CCl\]

    C) \[C{{H}_{3}}Cl>{{(C{{H}_{3}})}_{2}}CHCl>C{{H}_{2}}C{{H}_{2}}Cl>{{(C{{H}_{3}})}_{3}}CCl\]

    D) \[C{{H}_{3}}Cl>C{{H}_{3}}C{{H}_{2}}Cl>{{(C{{H}_{3}})}_{2}}CHCl>{{(C{{H}_{3}})}_{3}}CCl\]

    Correct Answer: D

    Solution :

    Order of reactivity of alkyl halide towards SN-2 reaction is \[C{{H}_{3}}X>{{1}^{o}}>{{2}^{o}}>{{3}^{o}}\]
