Concept introduction:
The structural formula is a simplified model that represents the arrangement of atoms and bonds in a molecule. Amines are derivative of ammonia obtained by substitution of hydrogen atom attached to the nitrogen atom by an alkyl group. Based on the alkyl groups, amines are classified as:
1. Primary amines: The nitrogen atom is attached to a alkyl group and 2 hydrogen atoms.
2. Secondary amines: The nitrogen atom is attached to a two alkyl groups and a hydrogen atom.
3. Tertiary amines: The nitrogen atom is attached to three alkyl groups and zero hydrogen atom.
The general name for amines is as follows,
Name of alkyl group + amine
