    The \[C{{N}^{-}}\] ion and \[{{N}_{2}}\] are isoelectronic. But in contrast to \[C{{N}^{-}},{{N}_{2}}\] is chemically inert because of-

    A) Low bond energy

    B) Absence of bond polarity

    C) Unsymmetrical electron distribution

    D) Presence of more number of electrons in bonding orbital

    Correct Answer: B

    Solution :

    [b] \[{{N}_{2}}\] is almost chemically inert because it has very high bond energy and absence of bond polarity.
