What property of alkali metals makes them strong reducing agents?

What property of alkali metals makes them strong reducing agents?

Options

  1. AHigh ionization enthalpy
  2. BLow sublimation enthalpy
  3. CHigh hydration enthalpy
  4. DLow electronegativity

Correct answer

C. High hydration enthalpy

Step-by-step solution

The high reducing power of alkali metals is primarily attributed to their high hydration enthalpy. This is because the small size of alkali metal ions, such as lithium (Li⁺), results in strong electrostatic attraction with water molecules, leading to a highly negative standard electrode potential (E0) and strong reducing properties.
