It is an experimental fact that `Cs_(2)[CuCl_(4)]` is orange coloured but `(NH_(4))_(2)[CiCl_(4)]` is yellow. It id further known that total paramagnetic moment of an unpaired electron is due to spin as well as due to nature of orbitlal, 'd' orbital contributing more than 's' or 'p' Thus the total paramagnetic moment of organe compound is found to be more than that of yellow compound. Then which of the following is correct.

Options

A. Anion of organe compound is tetrahedral and that of yellow is square planar.
B. Anion or orange compound is squance and that of yellow is tetrahedral.
C. Both the anions are terrahedral
D. Both the anion are square planar.

Explanation

(A) , In `[CuCl_(4)]^(2-)` orange compound there is one unpaired electron in d-orbital, therefore, its hybridisation is `sp^(3)` where as in `[CuCl_(4)]^(2-)` yellow compound, having `dsp^(2)` hybridisation. The size of the cation can influence the geometry of the anon.
