Options:
  • A Mn2+has a higher ionization energy than Fe2+.
  • B Mn2+compounds is already stable due to half-filled d-orbital but Fe2+compounds have six electrons in their 3d-orbital,so they want to get reduced to d5configuration
  • C Mn2+has a more stable electron configuration in the +3 state.
  • D Mn2+forms stronger bonds with ligands than Fe2+
