Why are Mn 2+ compounds more stable than Fe 2+ towards oxidation to their +3 state?

Options

  1. AMn 2+ has a higher ionization energy than Fe 2+ .
  2. BMn 2+ compounds is already stable due to half-filled d-orbital but Fe 2+ compounds have six electrons in their
  3. CMn 2+ has a more stable electron configuration in the +3 state.
  4. DMn 2+ forms stronger bonds with ligands than Fe 2+

Correct answer

B. Mn 2+ compounds is already stable due to half-filled d-orbital but Fe 2+ compounds have six electrons in their

Step-by-step solution

Correct Option is : (B) Mn 2+ compounds is already stable due to half-filled d-orbital but Fe 2+ compounds have six electrons in their 3d-orbital,so they want to get reduced to d 5 configuration
