The geometry of Ni (CO)4 and and Ni (P Ph3)2 Cl2 are

A.both square planar

B.tetrahedral and square planar, respectively

C.both tetrahedral✓ Correct

D.square planar and tetrahedral, respectively

Explanation

In 4 Ni(CO) the oxidation state of Ni is 0 and Co is a strong field ligand, the hybridization will be 3 sp and shape will be tetrahedral. In 3 2 2 Ni(PPh ) Cl the oxidation state of Ni is +2 and Cl is a weak field ligand Hence, the hybridization will be 3 sp and shape will be tetrahedral. Hence, the correct answer is option (c)
