Question

Ni(CO)4 and [Ni(NH3)4]2+ do not differ in

Solution

Correct option is

Magnetic moment

Ni (0):

Under the influence of strong field ligand CO, Ni(0) = (Ar)3d10sp3hybridisation and no unpaired electrons. Ni(II) = [Ar]3d8; under the inffluence of strong field ligand NH3.

Ni(II) = [Ar]

hybridisation and no unpaired electrons.
