NOTE : In metal carbonyl the metal is in zero oxidation state.
In Ni(CO)4 , O.N. of Ni = 0
For Ni (Z = 28)
In Ni(CO)4 , O.N. of Ni = 0
For Ni (Z = 28)
In presence of CO two 4s electrons pair up, thus
In Ni(PPh3)2Cl2, O.N. of Ni = +2 For Ni2+
PPh3 and Cl– can’t pair up d-electrons, leading to sp3 hybridization leading to tetrahedral geometry.

Ni(CO)4:
- Ni(CO)4 is the chemical formula for nickel tetracarbonyl.
- The central atom, nickel (Ni), is bonded to four carbon monoxide (CO) ligands.
- The geometry of Ni(CO)4 is tetrahedral.
- In a tetrahedral geometry, the central atom is surrounded by four ligands, which are positioned symmetrically around the central atom.
- The bond angles in a tetrahedral geometry are approximately 109.5°.
- Therefore, the correct answer is option 'c', both nickel tetracarbonyl (Ni(CO)4) and Ni(PPh3)2Cl2 have a tetrahedral geometry.
Ni(PPh3)2Cl2:
- Ni(PPh3)2Cl2 is the chemical formula for bis(triphenylphosphine)nickel(II) chloride.
- The central atom, nickel (Ni), is bonded to two triphenylphosphine (PPh3) ligands and two chloride (Cl) ligands.
- The geometry of Ni(PPh3)2Cl2 is square planar.
- In a square planar geometry, the central atom is surrounded by four ligands, which are positioned in a square arrangement around the central atom.
- The bond angles in a square planar geometry are 90°.
- Therefore, the correct answer is option 'c', both nickel tetracarbonyl (Ni(CO)4) and Ni(PPh3)2Cl2 have a tetrahedral geometry.
- Ni(CO)4 is the chemical formula for nickel tetracarbonyl.
