The chapter Amines in UP Board Class 12 Chemistry provides a detailed understanding of one of the most important classes of organic compounds derived from ammonia. Students learn about the classification of amines—primary, secondary and tertiary—based on the number of alkyl or aryl groups attached to the nitrogen atom. The chapter explains the nomenclature, structure, and physical properties of amines, helping students build a strong conceptual foundation.
A major focus is on the preparation of amines, such as reduction of nitro compounds, ammonolysis of alkyl halides, Gabriel phthalimide synthesis and Hoffmann bromamide degradation. Students also study the chemical reactions of amines, including basicity, alkylation, acylation, reaction with nitrous acid and electrophilic substitution in aromatic amines. The chapter ends with important applications of amines in the pharmaceutical, dye, polymer and pesticide industries.
