Chemical properties

An amphoteric oxide which can act like best oxidizing agent among the following is


A) CO…Neutral.

B) SiO…Exists at high temperature only.

C) GeO…Acidic

D) SnO, PbO….Amphoteric.

E) CO2…Most acidic oxide of 14th group

F) SiO2…Acidic

G) GeO2…Less acidic

H) SnO2, PbO2….Amphoteric.

I) Oxidizing power of PbO2>SnO2>GeO2>SiO2>CO2

   Due to inert pair effect Pb4+ is unstable and thus acts as oxidant.
