Explanation
Orbital angular momentum =h√2π
The orbital angular momentum =h√2π
From the structural point of the view, we see that,
NF3 is pyramidal whereas BF3 is planar triangular in structure.
BF−4 and NH+4 ions both are tetrahedral in structure.
BCl3 is triangular planar whereas BrCl3 is pyramidal in structure.
NH3 is pyramidal whereas NO3 is triangular planar structure.
So as we can see the only option B has both the elements same in structure.
The correct answer is option B.
Now for the other (anionic part):
Here the ligand is chloride. Since there are 4 chlorides so we’ll call it tetrachloride. We have the central metal atom as platinum again, but since it is in the anionic coordination sphere.
