. The hybridisation of Ni inNi(CO)4 is

Best Answer

Explanation:-

• The outer electronic configuration of Ni is 3d⁸4s² .
• Now ,Ni is in zero oxidation state. The 2 electrons from 4s orbitals moves to the 3d orbital and we get completely filled 3d orbital and vacant 4s and 4 p orbital. 

3d¹⁰4s⁰4d⁰

• This way we get sp³  hybridization and shape is tetrahedral.
• It does not have any unpaired electrons so it is diamagnetic in nature.

Final Answer:-

The hybridization of Ni in Ni(CO)₄   complex  is  (C ) sp³
