- B$CaO_2$
- ✓$PbO_2$
- D$H_2O_2$
✓
Answer
Correct option: C.
$PbO_2$
c
$PbO _2$ are not true peroxide because they do not liberate $H _2 O _2$ on treatment with dilute acids.
$PbO _2$ are not true peroxide because they do not liberate $H _2 O _2$ on treatment with dilute acids.
Lead $(IV)$ oxide and the lead atom shares its $4$ electrons $2$ each with oxygen atoms. In Peroxide there a bond sharing of two oxygen atoms as in:
Hydrogen Peroxide $H - O - O - H$
Water is an oxide $H - O - H$
Likewise $PbO _2$ is an oxide $P$ b has a valency $4$
$O = Pb = O$
