$[NiCl_4]^{2-}$

Vedclass · Answer

(D) In $[NiCl_4]^{2-}$,the oxidation state of $Ni$ is $+2$ ($3d^8$ configuration). $Cl^-$ is a weak field ligand,so it does not cause pairing of electrons. Thus,the hybridization is $sp^3$,which results in a tetrahedral geometry. In contrast,$[PdCl_4]^{2-}$,$[Ni(CN)_4]^{2-}$,and $[Pd(CN)_4]^{2-}$ involve strong field ligands or $4d/5d$ metals,leading to $dsp^2$ hybridization and square planar geometry.

Which of the following compounds has a tetrahedral geometry?
