A compound $\left(M_2 \mathrm{O}_2\right)$ of group I element $(M)$ hydrolyses to form $M^{+}, \mathrm{OH}^{-}$and $X$. Another compound $\left(M^{\prime} \mathrm{O}_2\right)$ of group I element $\left(M^{\prime}\right)$ hydrolyses to form $\left(M^{\prime}\right)^{+}, \mathrm{OH}^{-}, X$ and $Y$. What are $X$ and $Y$ respectively ?
  1. $\mathrm{H}_2 \mathrm{O}_2, \mathrm{O}_2$
  2. $\mathrm{O}_2, \mathrm{H}_2$
  3. $\mathrm{H}_2 \mathrm{O}_2, \mathrm{O}_3$
  4. $\mathrm{H}_2, \mathrm{H}_2 \mathrm{O}_2$

Solution

$M_2 \mathrm{O}_2 \longrightarrow M^{+}+\mathrm{OH}^{-}$and $x=\left(\mathrm{H}_2 \mathrm{O}_2\right.$ peroxide $)$ $ M^{\prime} \mathrm{O}_2 \longrightarrow M^{+}+\mathrm{OH}^{\prime}, M^{\prime}+\mathrm{O}_2 y=\left(\mathrm{O}_2=\text { Oxygen }\right) $
