Why does Fe have a comparatively low Eo value?

Options

  1. AThe removal of an electron from the stable d10 configuration of Fe2+
  2. BThe stability of Fe3+ with a noble gas configuration
  3. CThe half-filled t 2g level of Fe2+
  4. DThe removal of an electron from the d5 configuration of Fe2+

Correct answer

B. The stability of Fe3+ with a noble gas configuration

Step-by-step solution

The paragraph mentions that the comparatively low Eo value for Fe shows the extra stability of Fe3+ (d5).
