    The rate of free radical chlorination of\[C{{H}_{4}}\]is

    A)  equal to\[C{{D}_{4}}\]

    B)  double the rate of \[C{{D}_{4}}\]

    C)  12 times the rate of\[C{{D}_{4}}\]

    D)  less than the rate of\[C{{D}_{4}}\]

    Correct Answer: C

    Solution :

     The rate of reaction of\[C{{H}_{4}}\]is greater than \[C{{D}_{4}}\]because the activation energy of\[C{{H}_{4}}\]is less than the\[C{{D}_{4}}\]. Hence, the rate of free radical chlorination of\[C{{H}_{4}}\]is greater than\[C{{D}_{4}}\].
