Question

What is the shape and magnetic nature of permanganate ion ? (A) Pyramidal diamagnetic (B) Tetrahedral, diamagnetic (C) Tetrahedral, paramagnetic (D) Planar, paramagnetic

Tardigrade Admin · Accepted Answer

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: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/cef2abf918e14668a338b59fb59f03cb-.png" />

Pyramidal diamagnetic

Tetrahedral, diamagnetic

Tetrahedral, paramagnetic

Planar, paramagnetic

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:
