An organic compound $${}^{\prime }{\mathrm{A}}^{\prime }$$ contains nitrogen and chlorine. It dissolves readily in water to give a solution that turns litmus red. Titration of compound $${}^{\prime }{\mathrm{A}}^{\prime }$$ with standard base indicates that the molecular weight of $${}^{\prime }{\mathrm{A}}^{\prime }$$ is $$131\pm 2$$. When a sample of $${}^{\prime }{\mathrm{A}}^{\prime }$$ is treated with aq. $$\mathrm{NaOH}$$, a liquid separates which contains $$\mathrm{N}$$ but not $$\mathrm{Cl}$$. Treatment of the obtained liquid with nitrous acid followed by phenol gives orange precipitate. The compound $${}^{\prime }{\mathrm{A}}^{\prime }$$ is :
