Study Notes
Introduction to Heterocyclic Chemistry
- Heterocyclic compounds contain rings with at least one atom that is not carbon (Z can be N, O, S, etc.).
- These compounds differ from homocyclic compounds, where the ring consists solely of carbon atoms.
Definitions
- Homocyclic compounds: Organic compounds with cyclic structures made entirely of carbon atoms (e.g., benzene).
- Heterocyclic compounds: Organic compounds with cyclic structures containing at least one carbon atom and at least one heteroatom (N, O, S).
Characteristics of Heterocyclic Compounds
- Heterocyclic rings can consist of three or more atoms.
- They may be saturated or unsaturated.
- Can contain multiple heteroatoms, which can be either the same or different.
Types of Cyclic Compounds
- Isocyclic or carbocyclic compounds refer to cyclic structures made up of only carbon atoms.
