  • question_answer The cyanide ion, \[C{{N}^{-}}\] 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 orbitals

    Correct Answer: B

    Solution :

    Both \[CN\] and \[{{N}_{2}}\] molecules have the same \[MO\] diagrams but differ only in bond polarity. Thus \[{{N}_{2}}\]. is inert due to absence of bond polarity while CN ion is reactive due to presence of bond polarity.
