Nitrous acid reacts with all classes of amines. The products obtained from there reactions depend on whether the amine is primary, secondary or tertiary and whether the amine is aliphatic or aromatic. Aliphatic primary amines reacts with nitrous acid ( NaNO 2+ HCl ) to form alcohol as major product. In addition to alcohol, alkene and alkyl halides are also formed as minor product. Certain cyclic primary amines can undergo either ring expension or ring contraction reactions on treatment with nitrous acid. The reaction is called Demjanor ring expansion or contraction What will be the major product when 2 -amino propane is treated with nitrous acid?
