Why does Zn have the highest Eo value?

Options

  1. AThe removal of an electron from the stable d10 configuration of Zn2+
  2. BThe half-filled t 2g level of Zn2+
  3. CThe removal of an electron from the d5 configuration of Zn2+
  4. DThe stability of Zn3+ with a noble gas configuration

Correct answer

A. The removal of an electron from the stable d10 configuration of Zn2+

Step-by-step solution

The highest Eo value for Zn is due to the removal of an electron from the stable d10 configuration of Zn2+.
