In this presentation, I have tried to explain the basics of amino acids. it also includes the main reactions of amino acids.

1. Amino Compounds

2. Amines
• Amines are ammonia (NH) derivative compounds. In which one or more
hydrogen atoms are replaced by alkyl group.
On the basis of attached alkyl groups to the nitrogen atom, Amines are
classified as primary (1o), secondary (2o), and tertiary (3o).
• Primary amines : has only one alkyl group directly attached to N atom.
(R-NH2).
• Secondary amines : has two alkyl groups directly attached to N atom
(R2NH).
• Tertiary amines: has three alkyl groups directly attached to N atom
(R3N).

5. Nomenclature
1. Amines are named by naming the alkyl groups attached to the N atom followed by the ending amine.
Methylamine
2. The prefix di or tri is added when there are two or three identical alkyl groups directly attached to the N atom.
Dimethylamine Trimethylamne
3. If two or three different alkyl groups are attached to N atom they are named in alphabetical order.
5-Methyl-3-aminohexane
Ethylamine

31. Physical Properties
• Amines are moderately polar substances; they have boiling points
that are higher than those of alkanes but generally lower than those
of alcohols of comparable molecular weight. Molecules of primary
and secondary amines can form strong hydrogen bonds to each other
and to water. Molecules of tertiary amines cannot form hydrogen
bonds to each other, but they can form hydrogen bonds to molecules
of water or other hydroxylic solvents.
• As a result, tertiary amines generally boil at lower temperatures than
primary and secondary amines of comparable molecular weight, but
all low-molecularweight
• amines are very water soluble.
