Why are `Mn^(2+)` compounds more stable than `Fe^(2+)` toward oxidation to their `+3` state?

Text Solution

Verified by Experts

`Mn^(2+)=3d^5`, which is half-filled and hence stable.Therefore, `IE_3` is very high, i.e., 3rd electron cannot be lost easily. `Fe^(2+)=3d^6`, hence, it can lose one electron easily to give the stable configuration `3d^5`.
