Ge (II) compounds are powerful reducing agents whereas Pb (IV) compounds are strong oxidants. It can be because

Options

  1. APb is more electropositive than Ge .
  2. Bionisation potential of lead is less than that of Ge.
  3. Cionic radii of Pb ²⁺ and Pb ⁴⁺ are larger than that of Ge ²⁺ and Ge ⁴⁺
  4. Dmore pronounced inert pair effect in lead has.

Correct answer

D. more pronounced inert pair effect in lead has.

Step-by-step solution

Inert pair effect is more pronounced in heavier members like Pb. Hence, Pb (IV) compounds act as strong oxidising agents and are reduced to more stable Pb (II) compounds.
