    The correct order of increasing bond length of \[C-H,C-O,C-C\]and\[C=C\]is

    A) \[C-C<C=C<C-O<C-H\]

    B) \[C-O<C-H<C-C<C=C\]

    C) \[C-H<C-O<C-C<C=C\]

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

    Correct Answer: D

    Solution :

    C?H: 0.109 nm C = C : 0.134 nm C?O : 0.143 nm C?C : 0.154 nm \[\therefore \]Bond length order is C?H < C = C < C? O < C ? C
