  • question_answer
    The common features among the species \[C{{N}^{-}}\], CO  and \[N{{O}^{+}}\] are                        [IIT Screening 2001]

    A)                 Bond order three and isoelectronic

    B)                 Bond order three and weak field ligands

    C)                 Bond order two and p-acceptors

    D)                 Isoelectronic and weak field ligands

    Correct Answer: A

    Solution :

               Each of the species has 14 electron so isoelectronic and shows bond order 3.                                 B.O.\[=\frac{1}{2}[{{N}_{b}}-{{N}_{a}}]\]\[=\frac{1}{2}[10-4]=\frac{6}{2}=3\].
