Write the reaction of (i)aromatic and (ii) aliphatic primary amines with nitrous acid ?
Aromatic primary amines reacts with HNO2 at 273-278K to form aromatic diazonium salts.
aliphatic Primary amines also react with HNO2 at 273-278 K to form aliphatic diazonium salts. But these are unstable even at this low temperature and thus decompose readily to form a mixture of compounds consisting of alkyl chlorides, alkenes and alcohols,out of which alcohols generally predominates.
