Which of the following is not isostructural with `SiCI_(4)` ?

Options

A. `PO_4^(3-)`
B. `NH_4^(+)`
C. `SCl_4`
D. `SO_4^(2-)`

Answer

C

Explanation

`SN` of `Si` in `SiCl_4` is `4+0=4`, therefore, it is tetrahedral. `SN` of `P` in `PO_4^(3-)` is `4+0=4` (tetrahedral), `SN` of `N` in `NH_4^(+)` is `4+0=4` (tetrahedral), `SN` of `S` in `SCl_4` is `4+1=5` (seesaw), and `SN` of `S` in `SO_4^(2-)` is `4+0=4` (tetrahedral).
