Explain how does the presence or absence of hydrogen on N of amines affect the modes of their reactions with nitrous acid?
mention the chief use of quaternary ammonium salts derived from long chain amines.
The quaternary ammonium salts derived from long chain aliphatic amines are used as detergents. i.e. CH3(CH2)15N+(CH3)2Cl-

(i) Ethyldimethyl amine
(ii) n-butyl amine
(iii) diethyl amine
in order of decreasing boiling point and give reason.
