Options
Pyramidal diamagnetic
Tetrahedral, diamagnetic
Tetrahedral, paramagnetic
Planar, paramagnetic
MCQ
Solution
Tetrahedral, diamagnetic
Explanation:
The ions of permanganate are tetrahedral. The π- bonding occurs when the p-orbitals of oxygen collide with the d-orbitals of manganese. Because there are no unpaired electrons, it is also diamagnetic. The following is the structure of the permanganate ion:
