Write the reactions of aromatic and aliphatic primary amines withnitrous acid. |
Answer» Solution : AROMATIC primary amines reacts with `HNO_2`at 273-278 to from aromatic DIAZONIUM salts.  Aliphatic primary amines also react with HNO.. at 273-278 K to form aliphatic diazonium salts . But these are unstable even at low temperature and THUS decomposers readily to form a mixture of compounds CONSISTING of alkyl chlorides , alkenes and alcohols , out of which alcohols generally predominates. `underset("Ethylamine")(CH_3CH_2NH_2)+NHO_2+HCloverset(-2H_2O)underset(273-278K)rarrunderset(("unstable"))underset("Ethanediazonium chloride")([CH_3CH_2-overset(+)N-=N]Cl^(-))overset(H_2O)rarrunderset("Ethanol")(CH_3CH_2OH)+N_2+HCl` |
