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.
