Redox and Equivalent ConceptMedium

Question

Ge (II) compounds are powerful reducing agents whereas Pb (IV)compounds are strongoxidants. It can be due to.

Options

A.Pb is more electron positive then Ge
B.Ionization potential of lead is less than that of Ge
C.Ionic radii of Pb2+ and Pb4+ are larger than those of Ge2+ and Ge4+
D.More pronounced inert pair effect in lead than in Ge

Solution

Ge (II) tends to acquire Ge (IV) state by loss of electrons. Hence it is reducing in nature. pb (IV) tends to acquire pb (II) O.S. by gain of electrons. Hence it is oxidizing in nature. Thus is due to inert pair effect.
