    Arrange the (C - H) bonds x, y and z in decreasing order of their bond dissociation energies in homolysis.

    A) \[y>x>z\]

    B) \[z>x>y\]

    C) \[z>y>x\]

    D) \[y>z>x\]

    Correct Answer: B

    Solution :

    So bond dissociation enegy order is
    \[{{\operatorname{E}}_{1}}<{{E}_{2}}<{{E}_{3}}i.e,\left( z \right)>\left( x \right)>\left( y \right)\]
