    Which of the following is paramagnetic?

    A)  \[N{{H}_{2}}OH\]       

    B)  \[{{N}_{2}}{{O}_{3}}\]

    C)  \[N{{O}_{2}}\]         

    D)  \[{{N}_{2}}{{H}_{6}}C{{l}_{2}}\]

    Correct Answer: C

    Solution :

     The total valence electron present in\[N{{O}_{2}}\]are 17 which is an odd number. Therefore, it will be paramagnetic in character. All other have even number (14 in\[N{{H}_{2}}OH,\]28 in\[{{N}_{2}}{{O}_{3}}\]and 30 in\[{{N}_{2}}{{H}_{6}}C{{l}_{2}}\]) of electrons and are diamagnetic.
