    Which of the following, cations is not paramagnetic?

    A)  \[S{{C}^{3+}}(aq)\]                        

    B)  \[T{{i}^{3+}}(aq)\]

    C)  \[{{V}^{3+}}(aq)\]                          

    D)  \[C{{r}^{3+}}(aq)\]

    Correct Answer: A

    Solution :

                    \[Sc=1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}3{{d}^{1}}4{{s}^{2}}\] \[S{{c}^{3+}}=1{{s}^{2}}2{{s}^{2}}2{{p}^{6}}3{{s}^{2}}3{{p}^{6}}\] Since, there is no unpaired electron, hence \[S{{c}^{3+}}\]is not a paramagnetic ion.
