Which factor makes Li the strongest reducing agent in aqueous solution?

Which factor makes Li the strongest reducing agent in aqueous solution?
  1. Sublimation enthalpy
  2. lonisation enthalpy
  3. Hydration enthalpy
  4. Electron gain enthalpy

Solution

Lithium has highest hydration enthalpy, which accounts for its high negative \(E^{\circ}\) value and its high reducing power. Hence, the correct option is (c).
