The species having tetrahedral shape is

Options

A. `[PdCl_(4)]^(2-)`
B. `[Ni(CN)_(4)]^(2-)`
C. `[Pd(CN)_(4)]^(2-)`
D. `[NiCl_(4)]^(2-)`

Answer

4

Explanation

In `[NiCl_(4)]^(2-)`, the `Ni` is in `+2` oxidation state

`Cl^(-)` is a weak field ligand . So

Hence the shape is tetrahedral and complex is paramagnetic with two unparied electrons.

`[PdCl_(4)]^(2-),[Ni(CN)_(4)]^(2-)` and `[Pd(CN)_(4)]^(2-)` are square planar
