Question

The manganate and permanganate ions are tetrahedral due to ______.

Options

• The π-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese.

• There is no π-bonding.

• The π-bonding involves overlap of p-orbitals of oxygen with p-orbitals of manganese.

• The π-bonding involves overlap of d-orbitals of oxygen with d-orbitals of manganese.

Answer 1

The manganate and permanganate ions are tetrahedral due to the π-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese.

Explanation:

In \[\ce{MnO^{2−}_4}\] (manganate) and MnO⁴⁻ (permanganate) ions, the shape is tetrahedral. This shape is because of π-bonding between the p-orbitals of oxygen and the d-orbitals of manganese. This p-d π-bonding helps in holding the oxygen atoms around the manganese atom in a tetrahedral arrangement.
