If aniline is treated with \(1: 1\) mixture of conc. \(\mathrm{HNO}_3\) and conc. \(\mathrm{H}_2 \mathrm{SO}_4\), p-nitroaniline and \(m\)-nitroaniline are formed nearly in equal amounts. This is due to

Which of the following is least soluble in water at \(298 \mathrm{~K}\) ?

The final product for the reaction is

Hinsberg's reagent is

\(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{Cl} \xrightarrow{\text { Alc. } \mathrm{NH}_3} A \xrightarrow{2 \mathrm{CH}_3 \mathrm{Cl}} B.\) The product \(B\) is

A hydrocarbon \(A\left(\mathrm{C}_4 \mathrm{H}_8\right)\) on reaction with \(\mathrm{HCl}\) gives a compound \(\mathrm{B}\left(\mathrm{C}_4 \mathrm{H}_9 \mathrm{Cl}\right)\) which on reaction with \(1 \mathrm{~mol}\) of \(\mathrm{NH}_3\) gives compound \(\mathrm{C}\left(\mathrm{C}_4 \mathrm{H}_{10} \mathrm{N}\right)\). On reacting with \(\mathrm{NaNO}_2\) and \(\mathrm{HCl}\) followed by treatment with water, compound \(C\) yields an optically active compound \(D\). The compound \(D\) is
