Amines
Fish smells sharp because of amines, and many medicines and dyes contain nitrogen. This chapter in NCERT Class 12 Chemistry, Chapter 9, studies amines through structure, classification, naming, preparation by reduction and Hoffmann bromamide reaction, and basic character shaped by substituents. It explains diazonium salts, coupling reactions, tests that separate primary, secondary and tertiary amines, and uses in drugs and fibres. You will learn to compare basic strength and to follow conversions across nitrogen compounds.
