$[Ni(CO)_4]$

Vedclass · Answer

(C) The complex $[Ni(CO)_4]$ involves $Ni$ in the $0$ oxidation state. The electronic configuration of $Ni$ is $[Ar] 3d^8 4s^2$. In the presence of strong field ligand $CO$,the $4s$ electrons pair up into the $3d$ orbitals,resulting in a $3d^{10}$ configuration. This leads to $sp^3$ hybridization,which corresponds to a tetrahedral geometry. Since all electrons are paired,it is diamagnetic. The other options like $[NiCl_4]^{2-}$ are tetrahedral but paramagnetic due to the presence of unpaired electrons in the $3d$ orbitals.

Which of the following compounds is diamagnetic and tetrahedral?
