What is the shape and magnetic nature of permanganate ion?
- A Pyramidal diamagnetic
- B Tetrahedral, diamagnetic
- C Tetrahedral, paramagnetic
- D Planar, paramagnetic
Answer & Solution
Correct Answer
(B) Tetrahedral, diamagnetic
Step-by-step Solution
Detailed explanation
The permanganate ions are tetrahedral. The 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:
