In the reaction sequence,
$\mathrm{C}_2 \mathrm{H}_5 \mathrm{Cl}+\mathrm{KCN} \stackrel{\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}}{\longrightarrow} X \underset{\Delta}{\stackrel{\mathrm{H}_3 \mathrm{O}^{\oplus}}{\longrightarrow}} Y$
What is the molecular formula of $Y$ ?
$\mathrm{C}_3 \mathrm{H}_6 \mathrm{O}_2$
$\mathrm{C}_3 \mathrm{H}_5 \mathrm{~N}$
$\mathrm{C}_2 \mathrm{H}_4 \mathrm{O}_2$
$\mathrm{C}_2 \mathrm{H}_6 \mathrm{O}$
Solution
$\mathrm{C}_2 \mathrm{H}_5 \mathrm{Cl}+\mathrm{KCN} \stackrel{\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}}{\longrightarrow} \mathrm{C}_2 \mathrm{H}_5 \mathrm{CN} (X)+\mathrm{KCl}$
So, the molecular formula of the $Y$ is $\mathrm{C}_3 \mathrm{H}_6 \mathrm{O}_2$.
