Ge (II) compounds are powerful reducing agents whereas Pb (IV) compounds are strong oxidants. It is due to -
A
Pb is more electropositive than 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
Answer
More pronounced inert pair effect in lead than in Ge
Explanation
Solution
Ge4+ > Ge2+ (order of stability)
\ Ge2+ act as good reducing agent
while Pb2+ > Pb4+ (inert pair effect)
\ Pb4+ act as good oxidising agent
Pb4+ + 2e– ¾® Pb2+
