Nitrous acid reacts with all classes of amines. The product obtained from these reactions depend on whether primary, secondary or tetriary and ,wheather the amine or aliphatic or aromatic. Aliphalic primary amines react with 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 expansion or ring contraction reactions on treatment with acid. This reaction is called Demajanov ring expansion or contraction. What will be the major product when 2-aminopropane is treated with nitrous acid?

Oxidation and reduction process involves the transaction of electrons. Loss of electrons is oxidation and the gain of electrons is reduction. It is thus obvious that in a redox reaction, the oxidant is reduced by accepting the electrons and the reductant is oxidised by losing electrons. The reactions in which a species disproportionates into two oxidation states (lower and higher) are called disproportionation reactions. In electrochemical cells, redox reaction is involved, i.e., oxidation takes place at anode and reduction at cathode. Select the correct statement:
