    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.
