The structures of Ni(CO)4 and Ni(PPh3)2Cl2 are

A.square planar

B.tetrahedral and square planar respectively

C.tetrahedral✓ Correct

D.square planar and tetrahedral respectively

Explanation

[Ni(CO)4] Ni → 3d84s2 In [Ni(CO)4] Ni → 3d104s04p0 due to strong ligand CO. So hybridisation of [Ni(CO)4] sp3, [Ni(Ph3P)2(Cl)2] is tetrahedral due to bulky ligand Ph3P.
