9.5 Explain on the basis of valence bond theory that ion with square planar structure is diamagnetic and the
ion with tetrahedral geometry is paramagnetic.
Answers (1)
In both the compounds, the oxidation state of Nickel is +2. So it has d8 configuration.
Now, on the basis of ligand pairing of electrons will occur. Since CN- is a strong ligand so pairing will occur but in case of Cl- pairing will not be there as it is a weak ligand. So, the configuration of both the compounds looks like :-
Thus is a square planer and diamagnetic and
has tetrahedral geometry and is paramagnetic.
