Solution
The correct option is B 4 As the Co3+ has configuration as follows: 3d64s0 ,
Now,
as the F− is the weak field ligand, so it does not cause the
paring of the 3d6 electrons and it has 1 paired electrons and 4 unpaired
electrons in 3d orbitals.
In [CoF6]3−,Co3+ uses outer d orbitals (4d) in sp3d2 hybridization. The number of unpaired electrons present in complex ion is 4.
