Question

2. Discuss the stability order of following(4)
1 CO2, SiO2, GeO2, SbO2,PbO2​

Answer 1

Explanation:

CO

2

​

 and SiO

2

​

 are acidic due to electron deficiency.

SnO

2

​

 is amphoteric in nature as it can work as acid as well as base.

PbO

2

​

 is an oxidising agent because as move down the group oxidation state II become more stable so Pb II is more stable than Pb IV has due to this reason PbO

2

​

 has tendency to get electron and works as oxidising agent.
