Document Summary
Most organic bases are amines, which are compounds that are structurally derived by replacing one or more hydrogen atoms of ammonia with hydrocarbon groups. Amines are bases, because the nitrogen atom has an unshared electron pair that can accept a proton to form a substituted ammonium ion. Amides are compounds derived from the reaction of ammonia, or of a primary or secondary amine, with a carboxylic acid. For example, when ammonia is strongly heated with acetic acid, they react to give the amide acetamide. Amines are derivatives of ammonia (nh3) in which one or more hydrogen atoms are replaced by alkyl or aryl groups. Amines are classified into three different types as primary (10), secondary (20) and tertiary (30) depending on the number of hydrogen atoms replaced by alkyl or aryl groups. In primary amines, only one alkyl or aryl group is attached to the nitrogen atom.
