  • question_answer
    Bond energies in \[NO,\,N{{O}^{+}}\] and \[N{{O}^{-}}\] are such as [Pb. CET 2004]

    A)                 \[N{{O}^{-}}>NO>N{{O}^{+}}\] 

    B)                 \[NO>N{{O}^{-}}>N{{O}^{+}}\]

    C)                 \[N{{O}^{+}}>NO>N{{O}^{-}}\] 

    D)                 \[N{{O}^{+}}>N{{O}^{-}}>NO\]

    Correct Answer: C

    Solution :

                    Bond order of \[N{{O}^{+}},NO\] and \[N{{O}^{-}}\] are \[3,\ 2.5\]and 2 respectively, bond energy \[\propto \]bond order
