Ni (28):[ Ar ] 3 d 8 4 s 2 ∵ CO is a strong field ligand Configuration would be:

For, four 'CO' -ligands hybridisation would be sp 3 and thus the complex would be diamagnetic and of tetrahedral geometry.

Q. The geometry and magnetic behaviour of the complex $[N i (CO)_{4}]$ are

tetrahedral geometry and paramagnetic

square planar geometry and diamagnetic

square planar geometry and paramagnetic

tetrahedral geometry and diamagnetic

$N i (28) : [A r] 3 d^{8} 4 s^{2}$

$∵ CO$ is a strong field ligand

Configuration would be :

For, four $^{'} C O^{'}$ -ligands hybridisation would be $s p^{3}$ and thus the complex would be diamagnetic and of tetrahedral geometry.
