Fill in the blanks:
Compounds that formally contain `Pb^(4+)` are easily reduced to `Pb^(2+)`. The stability of the lower oxidation state is due to………… .

Text Solution

Verified by Experts

The correct Answer is:
Inert Pair Effect
Due to inert pair effect, `Pb^(2+)` (two less than normal oxidation state) is more stable than `Pb^(4+)` (normal oxidation state).
