JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure / रासायनिक आबंधन एवं आणविक संरचना Question Bank Self Evaluation Test - Chemical Bonding and Molecular Structure

  • question_answer
    Among the following, the species having the smallest bond is

    A) \[N{{O}^{-}}\]            

    B) \[N{{O}^{+}}\]

    C) \[O{{  }_{2}}\]                      

    D) \[NO\]

    Correct Answer: B

    Solution :

    [b] \[N{{O}^{-}}\left( 16 \right)-B.O.-2\] \[{{O}_{2}}\left( 16 \right)-B.O.-2\] \[N{{O}^{+}}(14)-B.O.-3\] \[NO\left( 15 \right)-B.O.-2.5\] Higher the bond order lower is the bond length. Hence \[N{{O}^{+}}\]will have smallest bond.
