285618 The method by which aniline cannot be prepared is

285619 A hydrocarbon\(A\left(\mathrm{C}_4 \mathrm{H}_8\right)\) on reaction with HCl gives a compound \(B\left(\mathrm{C}_4 \mathrm{H}_9 \mathrm{Cl}\right)\) which on reaction with 1 mol of \(\mathrm{NH}_3\) gives compound \(C\left(\mathrm{C}_4 \mathrm{H}_{11} \mathrm{~N}\right)\). On reacting with \(\mathrm{NaNO}_2\) and HCl followed by treatment with
water, compound \(C\) yields an optically active compound \(D\). The compound \(D\) is
Ans:b
Exp:(b) For obtaining optically active carbon, -Cl should be present on \(2^{\circ}\) carbon.
