Amines are an important class of organic compounds. They are widely found in both plants and animals. They are found among proteins, vitamins, alkaloids, hormones, etc. Synthetic examples include polymers, drugs, dyestuff, etc. These amines are widely used. For example, quinine is an important anti-malarial drug, adrenaline and ephedrine are used to raise blood pressure, Novocaine is used as an anesthetic in dentistry, codeine is used as an analgesic (as a pain reliever). Benadryl is used as an antihistamine drug. Quaternary ammonium salts are used as surfactants. Amines are considered to be derivatives of ammonia in which one, two, or all three hydrogen atoms are replaced by an alkyl or aryl group. Classification of Amines Amines are broken down as primary (1°), secondary (2°), or tertiary (3°) because one, two, or three hydrogens of the ammonia molecule are displaced by alkyl or aryl groups in the ammonia molecule. However, we get RNH, or ArNH 2 if one hydrogen atom of ammonia...
