Starting from propanoic acid, the following reactions were carried out: Propanoic acid $\stackrel{{\mathrm{SOCl}}_2}{⟶}\mathrm{X}\stackrel{{\mathrm{NH}}_3}{⟶}\mathrm{Y}\stackrel{{\mathrm{Br}}_2+\mathrm{KOH}}{⟶}\mathrm{Z}$. What is the compound $\mathrm{Z}$?

The major products $\mathrm{X}, \mathrm{Y}$ and $\mathrm{Z}$ in the following sequence of transformations

 are:

An aromatic amine $\left(\mathrm{X}\right)$ was treated with alcoholic potash and another compound $\left(\mathrm{Y}\right)$, then the foul smelling gas ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{NC}$ is formed. The compound $\left(\mathrm{Y}\right)$ was formed by reacting compound $\left(\mathrm{Z}\right)$ with ${\mathrm{Cl}}_2$ in the presence of slaked lime. The compound $\left(\mathrm{Z}\right)$ is:

Aniline, in a set of reactions yields a product $\mathrm{D}$. The structure of the product $\mathrm{C}$ would be :

 $\underset{\mathrm{HCl}}{\overset{{\mathrm{NaNO}}_2}{\to }}\mathrm{A}\stackrel{\mathrm{CuCN}}{⟶}\mathrm{B}\stackrel{{\mathrm{H}}_2,\mathrm{Ni}}{⟶}\mathrm{C}\stackrel{{\mathrm{HNO}}_2}{⟶}\mathrm{D}$

The major product of the reaction between $\mathrm{m}$-dinitrobenzene with ${\mathrm{NH}}_4\mathrm{HS}$ is :

The product of the following reaction is  $\stackrel{{\mathrm{H}}_3{\mathrm{O}}^{+},\mathrm{\Delta }}{⟶} \stackrel{{\mathrm{NaNO}}_2/\mathrm{HCl}}{⟶} \stackrel{{\mathrm{KNO}}_2/{\mathrm{Cu}}^{+}}{⟶}$

The compound $\mathrm{X}\left({\mathrm{C}}_7{\mathrm{H}}_9\mathrm{N}\right)$ reacts with benzensulfonyl chloride to give $\mathrm{Y}\left({\mathrm{C}}_{13}{\mathrm{H}}_{13}{\mathrm{NO}}_2\mathrm{S}\right)$, which is insoluble in alkali. The compound $\mathrm{X}$ is
