    In which alkyl halide, \[{{S}_{N}}2\] mechanism is favoured maximum by

    A) \[C{{H}_{3}}Cl\]                     

    B) \[C{{H}_{3}}C{{H}_{2}}Cl\]

    C) \[{{\left( C{{H}_{3}} \right)}_{2}}CHCl\]          

    D) \[{{\left( C{{H}_{3}} \right)}_{3}}C-Cl\]

    Correct Answer: A

    Solution :

    \[{{S}_{N}}2\]: Substitution nucleophilic bimolecular order of different alkyl halides: \[1{}^\circ > 2{}^\circ  > 3{}^\circ \] \[{{S}_{N}}1\]: Substitution nucleophilic unimolecular order of different alkyl halides:\[3{}^\circ  > 2{}^\circ  > 1{}^\circ \].
