(D) $(P)$ Gabriel phthalimide synthesis is used for the preparation of aliphatic primary amines. Among the given options,$2$-phenylethanamine $(C_6H_5CH_2CH_2NH_2)$ is an aliphatic primary amine.$(Q)$ $2^{\circ}$-amines react with Hinsberg's reagent (benzenesulfonyl chloride) to form a sulfonamide that is insoluble in $NaOH$ because it lacks an acidic hydrogen on the nitrogen atom. $N$-ethylaniline $(C_6H_5NHC_2H_5)$ is a $2^{\circ}$-amine.$(R)$ Aromatic primary amines react with nitrous acid $(HONO)$ at low temperature $(273-278 \ K)$ to form diazonium salts,which undergo coupling reactions with $\beta$-naphthol in alkaline medium to form a red azo dye. $o$-ethylaniline is an aromatic primary amine.Therefore,the correct sequence is $(P) = 2$-phenylethanamine,$(Q) = N$-ethylaniline,$(R) = o$-ethylaniline. This corresponds to option $D$.
