What is the primary reason for lithium's high negative E o value and strong reducing power?

Options

  1. ALarge ion size
  2. BLow ionization enthalpy
  3. CHigh hydration enthalpy
  4. DHigh electronegativity

Correct answer

C. High hydration enthalpy

Step-by-step solution

Lithium's high negative E o value and strong reducing power are primarily due to its high hydration enthalpy, which is a result of its small ion size and strong electrostatic attraction with water molecules. This makes lithium an effective reducing agent.
