    The bond order in NO is 2.5 while that in \[N{{O}^{+}}\]is 3. Which of the following statements is true for these two species [AIEEE 2004]

    A)                 Bond length in \[N{{O}^{+}}\]is equal to that in \[NO\]  

    B)                 Bond length in \[NO\]is greater than in \[N{{O}^{+}}\]

    C)                 Bond length in \[N{{O}^{+}}\]is greater than in \[NO\]

    D)                 Bond length is unpredictable

    Correct Answer: B

    Solution :

                    Higher the bond order, shorter will be the bond length, thus \[N{{O}^{+}}\] having the higher bond order that is 3 as compared to \[NO\]having bond order 2 so \[N{{O}^{+}}\] has shorter bond length.
