The structure for acetaldehyde semicarbazone is:

$\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4}{⟶}\stackrel{{\mathrm{H}}_2\mathrm{O}}{⟶}\left(\mathrm{X}\right)+\left(\mathrm{Y}\right)$ Product $\left(\mathrm{X}\right)$ and $\left(\mathrm{Y}\right)$ are:

$\left[\mathrm{X}\right]\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }\underset{\left(\mathrm{ii}\right) {\mathrm{H}}^{+}}{\overset{\left(\mathrm{i}\right) \mathrm{KOH}}{\to }}\mathrm{Ph}-{\mathrm{NH}}_2+{\mathrm{CH}}_3\mathrm{COOH}$
