What is the shape and magnetic nature of permanganate ion?

Options

APyramidal diamagnetic
BTetrahedral, diamagnetic
CTetrahedral, paramagnetic
DPlanar, paramagnetic

Correct answer

B. Tetrahedral, diamagnetic

Step-by-step solution

The permanganate ions are tetrahedral. The π - bonding takes place by overlap of p- orbitals of oxygen with d- orbitals of manganese. It is also diamagnetic due to the absence of unpaired electron. The structure of permanganate ion is given below:
