    The ion that is isoelectronic with \[CO\] is

    A)  \[C{{N}^{-}}\]                   

    B)  \[O_{2}^{+}\]

    C)  \[O_{2}^{-}\]                                  

    D)  \[N_{2}^{+}\]

    Correct Answer: A

    Solution :

    \[Co\] has a total of 14 electrons and CN- also has 14 electrons hence they are isoelectronic. \[C\left( 6{{e}^{-}} \right)+N\left( 7{{e}^{-}} \right)+{{e}^{-}}\xrightarrow{{}}C{{N}^{-}}\left( 14{{e}^{-}} \right)\]
