    The order of reactivities of methyl halide in the formation of Grignard reagent is:

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

    B)  \[C{{H}_{3}}I>C{{H}_{3}}Br>C{{H}_{3}}Cl\]

    C)  \[C{{H}_{3}}Br>C{{H}_{3}}I>C{{H}_{3}}Cl\]

    D)  \[C{{H}_{3}}Br>C{{H}_{3}}Cl>C{{H}_{3}}I\]

    Correct Answer: B

    Solution :

     Order of electro negativities of halogens are: \[F>Cl>Br>I\] Hence, the order of reactivities of methyl halide in the formation of Grignard reagent is \[C{{H}_{3}}I>C{{H}_{3}}Br>C{{H}_{3}}Cl\]
