Amines and Their Reactions

Amine Group

• Contains the functional group -NH₂.

• Molecules with only an amine group belong to the amine homologous series.

Identification of Amines

• Molecules with only the -NH₂ group are classified as amines.

Preparation of Amines

• Amines can be synthesized by:

  • Reacting a halogenoalkane with ethanolic ammonia.

  • Requires: heat, high pressure, and excess ammonia.

Reactions Involving Amines

• Amines can be used to produce amides.

• Amides contain the functional group: R-C(=O)-NR'R".

• Preparation of amides involves:

  • Reacting an amine with an acyl chloride or an acid anhydride.
