(CO) carbonyl group being a strong ligand paired all electrons present in d orbital of Ni.
Hence form dsp2 hybrid orbitals and hence the shape of molecule is square planar.
In Ni(CO)4 complex, Ni will have 3d10 configuration. It has tetrahedral geometry but diamagnetic as there are no unpaired electrons.

Incorrect Statement Explanation:

Ni(CO)4 – Tetrahedral, paramagnetic
- The given statement is incorrect because Ni(CO)4 is actually a square planar complex with a diamagnetic nature.
- In the square planar geometry, the four CO ligands surround the nickel atom in a plane, giving it a square shape.
- Since all the electrons are paired in Ni(CO)4, it is diamagnetic and does not exhibit any paramagnetic behavior.

Correct Statements:
- [Ni(CN)4]2- – Square planar, diamagnetic
- Ni(CO)4 – Tetrahedral, diamagnetic
- [NiCl4]2- – Tetrahedral, paramagnetic
Therefore, the incorrect statement is option 'A' which states that Ni(CO)4 is tetrahedral and paramagnetic.
