Amongst Ni(CO)4, [Ni(CN)4]2- and [NiCl4]2- :

When two atomic orbitals join to generate a hybrid orbital in a molecule, the energy of the individual atoms' orbitals is redistributed to give orbitals of equivalent energy. This method is known as hybridization.Hybridization of [Ni(CO)4] is sp3 and [Ni(CN)4]2- is dsp3, since all the electrons are paired in both of these compounds they are diamagnetic while in[NiCl4]2-, Cl is a weak ligand and hence is unable to pair up all the electrons of 3d.Hence, the correct option is option (C) Ni(CO)4 and [Ni(CN)4]2- are diamagnetic and [NiCl4]2- is paramagnetic.

Detailed Solution

When two atomic orbitals join to generate a hybrid orbital in a molecule, the energy of the individual atoms' orbitals is redistributed to give orbitals of equivalent energy. This method is known as hybridization.
Hybridization of [Ni(CO)₄] is sp³ and [Ni(CN)₄]^2-is dsp³, since all the electrons are paired in both of these compounds they are diamagnetic while in[NiCl₄]^2-, Cl is a weak ligand and hence is unable to pair up all the electrons of 3d.

Hence, the correct option is option (C) Ni(CO)₄ and [Ni(CN)₄]^2- are diamagnetic and [NiCl₄]^2- is paramagnetic.
