$[Ni(CN)_4]^{2-}$

Vedclass · Answer

(B) $1$. In $[Ni(CN)_4]^{2-}$,the oxidation state of $Ni$ is $+2$. The electronic configuration of $Ni^{2+}$ is $[Ar] 3d^8$.$2$. $CN^-$ is a strong field ligand,which causes pairing of electrons in the $3d$ orbitals.$3$. This results in one empty $3d$ orbital,one $4s$ orbital,and two $4p$ orbitals,which undergo $dsp^2$ hybridization to form a square planar geometry.$4$. $[NiCl_4]^{2-}$ and $[Zn(NH_3)_4]^{2+}$ exhibit $sp^3$ hybridization (tetrahedral),while $[FeF_6]^{3-}$ exhibits $sp^3d^2$ hybridization (octahedral).

List-$I$ (Complex/Species)	List-$II$ (Shape and magnetic moment)
$A$. $[Ni(CO)_4]$	$I$. Tetrahedral,$2.8 \ BM$
$B$. $[Ni(CN)_4]^{2-}$	$II$. Square planar,$0 \ BM$
$C$. $[NiCl_4]^{2-}$	$III$. Tetrahedral,$0 \ BM$
$D$. $[MnBr_4]^{2-}$	$IV$. Tetrahedral,$5.9 \ BM$
