Heterocyclic Compounds

Cyclic compounds containing one or more heteroatoms in their rings are called heterocyclic compounds.

Atoms other than C and H are known as Heteroatoms.

Heterocyclic compounds are also divided into two categories

1. Alicyclic heterocyclic compounds.

2. Aromatic heterocyclic compounds.

Alicyclic heterocyclic compounds

Alicyclic compounds, containing one or more heteroatoms in their rings are called alicyclic heterocyclic compounds.

Examples of Alicyclic heterocyclic compounds

Alicyclic heterocyclic compounds example: Tetrahydrofuran
Alicyclic heterocyclic compounds example: Tetrahydrothiopene

Aromatic heterocyclic compounds

Aromatic cyclic compounds containing one or more heteroatoms in their molecules are called aromatic heterocyclic compounds.

Examples of Aromatic heterocyclic compounds.

Aromatic heterocyclic compounds example: Furan
Aromatic heterocyclic compounds example: Thiopene
