Why is manganese more stable in +2 state than in +3 state

Answers

Answered by Karu1405

Answer:

The electronic configuration of Mn2+ is [Ar] 3d5 while that of Mn3+ is [Ar] 3d4. Hence, manganese in the +2 oxidation state is more stable than +3 oxidation state due to half-filled d-orbitals. Hence, iron is stable at +3 oxidation state than +2 oxidation state due to half-filled d-orbitals.
