Chapter Summary

--- PAGE 1 --- Unit 9 Amines Objectives After studying this Unit, you will be able to • describe amines as derivatives of ammonia having a pyramidal structure; • classify amines as primary, secondary and tertiary; • name amines by common names and IUPAC system; • describe some of the important methods of preparation of amines; • explain the properties of amines; • distinguish between primary, secondary and tertiary amines; • describe the method of prepara- tion of diazonium salts and their importance in the synthesis of a series of aromatic compounds including azo dyes. "The chief commercial use of amines is as intermediates in the synthesis of medicines and fibres". Amines constitute an important class of organic compounds derived by replacing one or more hydrogen atoms of ammonia molecule by alkyl/aryl group(s). In nature, they occur among proteins, vitamins, alkaloids and hormones. Synthetic examples include polymers, dye stuffs and drugs. Two biologically ac…
