Which of the following are the correct products when the respective higher oxides of alkali metals a — s Block Elements Chemistry Question

💡 Solution & Explanation

Peroxides ($Na_2O_2$) hydrolyze to give metal hydroxide and hydrogen peroxide ($H_2O_2$). Superoxides ($KO_2$, $RbO_2$, $CsO_2$) hydrolyze to give metal hydroxide, $H_2O_2$, and oxygen gas ($O_2$). Normal oxides ($Li_2O$) give only metal hydroxide, making C incorrect.
