    The correct \[C-C\] bond length order is:
    \[\begin{matrix}    {{H}_{3}}C-C{{H}_{3}}  \\    (x)  \\ \end{matrix}\]    \[\begin{matrix}    {{H}_{3}}C-C{{H}_{2}}-Cl  \\    (y)  \\ \end{matrix}\]

    A) \[x>y\]

    B) \[x<y\]

    C) \[x=y\]

    D) \[C-C<C-H\]

    Correct Answer: B

    Solution :

    \[x=1.532\overset{{}^\circ }{\mathop{A}}\,\]     \[y=1.549\overset{{}^\circ }{\mathop{A}}\,\]     \[C-H=1.09\overset{{}^\circ }{\mathop{A}}\,\]
