Vedclass · Answer

(C) According to the spectrochemical series,$CN^-$ and $CO$ are strong field ligands,while $Cl^-$ is a weak field ligand. $Ni^{2+}$ $(3d^8)$ with four strong field ligands forms a square planar,diamagnetic complex like $[Ni(CN)_4]^{2-}$. $Ni(0)$ $(3d^8 4s^2)$ with four strong field ligands forms a tetrahedral,diamagnetic complex like $[Ni(CO)_4]$. $Ni^{2+}$ $(3d^8)$ with four weak field ligands $(Cl^-)$ forms a tetrahedral,paramagnetic complex $[Ni(Cl)_4]^{2-}$. In $[Ni(Cl)_4]^{2-}$,the $Ni^{2+}$ ion has an electronic configuration of $[Ar] 3d^8$. Due to the weak field ligand,no pairing occurs,resulting in two unpaired electrons in the $d$-orbitals,making it paramagnetic.

$B. SF_6$	$II. sp^3d$
$C. Ni(CO)_4$	$III. sp^3d^2$
$D. [PtCl_4]^{2-}$	$IV. sp^3$

Which of the following complexes formed by $Nickel$ is tetrahedral and paramagnetic?
