     The correct relation between the bond lengths a and b is:

    A) a = b

    B) b > a

    C) b < a

    D) Impossible to predict

    Correct Answer: B

    Solution :

    [b] \[C{{H}_{3}}-\overset{{{O}^{{{\delta }^{-}}}}}{\mathop{\overset{||}{\mathop{C}}\,}}\,=\overset{{{\delta }^{+}}}{\mathop{O}}\,-C{{H}_{3}}\] due to resonance this bond has partial double bond characters.
