Question

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

Solution

Correct option is

Both tetrahedral

 

Ni(CO)4 : tetrahedral (strong field ligand, CO, forces 4s2 electrons into 3dorbital  

      [NiP(Ph3)2Cl2] i.e., Ni(II) : 3d84s04p0   

(sp3 hybridisation as weak field ligands P’Ph3 and Cl do not force the two unpaired 3d electrons to be paired up.
