Alkali metals are powerful reducing agents because

Options

  1. Athey are metals
  2. Bthey are monovalent
  3. Ctheir ionic radii are large
  4. Dtheir ionisation energies are low

Correct answer

D. their ionisation energies are low

Step-by-step solution

Alkali metals have only one valence electron in their outermost shell. They loose one valence electron easily due to low ionisation enthalpy and get oxidised to reduces other compounds.
