9. Amines
Amines are derivatives of ammonia formed by replacing hydrogen atoms with alkyl or aryl groups, classified as primary, secondary, and tertiary. Their structure influences their physical and chemical properties, including basicity, boiling point, and solubility. Additionally, diazonium salts, obtained from aromatic amines, play a crucial role in synthesizing various organic compounds through substitution reactions.

What we have learnt
- Amines are classified based on the number of hydrogen atoms replaced.
- The boiling point of amines is influenced by hydrogen bonding.
- Diazonium salts are important intermediates in organic synthesis.
Key Concepts
- -- Amines
- Organic compounds derived from ammonia by substituting one or more hydrogen atoms with alkyl or aryl groups.
- -- Diazonium Salts
- Compounds containing a diazonium group (-N2+), formed by the reaction of nitrous acid with primary aromatic amines, used extensively in aromatic substitution reactions.
- -- Basicity of Amines
- Amines are basic due to the presence of an unshared electron pair on nitrogen, which can accept protons.
