The oxide that gives H_2 O_2 on treatment with dilute acid is

The oxide that gives H2O2\mathrm{H}_2 \mathrm{O}_2 on treatment with dilute acid is

Options

  1. APbO2\mathrm{PbO}_2
  2. BMnO2\mathrm{MnO}_2
  3. CNa2O2\mathrm{Na}_2 \mathrm{O}_2
  4. DTiO2\mathrm{TiO}_2

Correct answer

C. Na2O2\mathrm{Na}_2 \mathrm{O}_2

Step-by-step solution

Peroxides give hydrogen peroxide, on treatment with dilute acids. Hence, only sodium peroxide (Na2O2)\left(\mathrm{Na}_2 \mathrm{O}_2\right) will give H2O2\mathrm{H}_2 \mathrm{O}_2.
