                    Which of the following is not isostructural with \[SiC{{l}_{4}}\]?                                                                 

    A)                  \[SC{{l}_{4}}\]

    B)                  \[SO_{4}^{2-}\]               

    C)                  \[PO_{4}^{3-}\]              

    D)                  \[NH_{4}^{+}\]

    Correct Answer: A

    Solution :

                              \[SC{{l}_{4}}\] is not isostructural of \[SiC{{l}_{4}}\] because it shows square planar structure due to involvement of repulsion between lone pair and bond pair of electrons.                 \[SO_{4}^{2-}\] shows tetrahedral structure due to \[s{{p}^{3}}\] hybridisation                 \[PO_{4}^{3-}\] shows tetrahedral structure due to \[s{{p}^{3}}\] hybridisation                 \[NH_{4}^{+}\] shows tetrahedral structure due to \[s{{p}^{3}}\] hybridisation
