    Which of the following is diamagnetic?

    A)  \[{{S}^{-2}}\]                                    

    B)  \[O_{2}^{-}\]

    C)  \[N_{2}^{-}\]                                   

    D)  \[NO\]

    Correct Answer: A

    Solution :

                    Electronic configuration of \[{{S}^{-2}}\] is \[1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}\] Since, it has no unpaired electrons, thus it is diamagnetic.
