Study Notes
Definition and Classification of Amines
- Amines are organic compounds that contain a nitrogen atom bonded to one or more alkyl or aryl groups.
- They are formally derived from ammonia (NH3) by replacing one or more hydrogen atoms with hydrocarbon groups.
Substituents and Naming
- The substituent -NH2 is referred to as an amino group.
- Amino groups can be classified as primary, secondary, or tertiary based on the number of carbon-containing groups attached to the nitrogen.
Classification of Aliphatic Amines
- Aliphatic amines are classified based on the number of carbon atoms connected to the nitrogen atom:
- Primary amines have one carbon group attached.
- Secondary amines have two carbon groups attached.
- Tertiary amines have three carbon groups attached.
Compounds with Nitrogen and Carbonyl Group
- Compounds featuring a nitrogen atom attached to a carbonyl group are known as amides.
