Question

Why is manganese more stable in tha 2+ sttate than tha 3+ state and reverse is true for iron ?

Answer 1

Explanation:

Mn2+ is more stable than Mn3+ due to the stable electronic configuration ofMn2+ because of half filled d-orbital. Fe3+ is more stable than Fe2+ because Fe3+ has exactly half filled d- orbitals which give the stability to Fe3+ while Fe2+ has 3d6 electronic configuration.

Answer 2

Mn2+ is more stable than Mn3+ due to the stable electronic configuration ofMn2+ because of half filled d-orbital. Fe3+ is more stable than Fe2+ because Fe3+ has exactly half filled d- orbitals which give the stability to Fe3+ while Fe2+ has 3d6 electronic configuration.
