Why is Mn₃⁺ oxidizing?

Options

  1. ABecause its d4 configuration changes to d3.
  2. BBecause its d5 configuration changes to d4.
  3. CBecause its d3 configuration changes to d4.
  4. DBecause its d4 configuration changes to d5.

Correct answer

D. Because its d4 configuration changes to d5.

Step-by-step solution

The change from Mn₃⁺ to Mn₂⁺ results in the half-filled (d5) configuration, which has extra stability.
