- AminesAmines can be considered to be derivatives of ammonia in which one or more hydrogen atoms are replaced by alkyl or aryl groups.
- Properties of AminesAmmonia is a pyramidal molecule with bond angles of about 107° and amines therefore have this same shape.
- Basicity of AminesAmines have a lone pair of electrons and can act as proton acceptors (bases).
- Synthesis of AminesAliphatic amines can be prepared by gently warming halogenoalkanes with excess ammonia in an ethanol solvent.
- Reactions of Amines as BasesAmines react as bases with acids such as hydrochloric acid and nitric acid to form salts.
- Reactions of Amines as NucleophilesWhen ammonia in an ethanol solvent reacts with a halogenoalkane a primary amine is produced by the nucleophilic substitution of the halide by an NH2…
- Economic Importance of AminesAmines are used in the manufacture of medicines, dyes and plastics (polymers).
