Vedclass · Answer

(C) Among the given statements,only $(c)$ is true. Methylamine reacts with nitrous acid to liberate $N_2$ gas: $CH_3-NH_2 + HNO_2 	o CH_3OH + N_2 + H_2O$. Trimethylamine does not react with Hinsberg reagent $(C_6H_5SO_2Cl)$ in the presence of $KOH$ because it lacks an acidic hydrogen,and it remains insoluble. Dimethylamine reacts with Hinsberg reagent to form a sulfonamide which is insoluble in $KOH$. Azo dyes are typically formed by the coupling reaction of diazonium salts with phenols or aromatic amines,not by simple secondary amines.
