Square planar

Vedclass · Answer

(C) The complex ion is $[Ni(CN)_4]^{2-}$.In this complex,the oxidation state of $Ni$ is $+2$,which corresponds to the electronic configuration $[Ar] 3d^8$.$CN^-$ is a strong field ligand,which causes the pairing of electrons in the $3d$ orbitals.This results in $dsp^2$ hybridization.$dsp^2$ hybridization corresponds to a square planar geometry.

The tetracyanonickelate $(II)$ complex ion has a ..... geometry.
