Homocyclic Compounds

Previous Next

Homocyclic compounds contain rings which are made up of only carbon atoms. Homocyclic compounds are also known as carbocyclic compounds. Homocyclic compounds are further divided into following categories.

  1. Alicyclic homocyclic compounds.
  2. Aromatic homocyclic compounds

Alicyclic homocyclic compounds

Homocyclic compounds which resemble acyclic compounds in most of their properties are called alicyclic homocyclic compounds.

Example : Cyclohexane

Homocyclic compounds example : cyclohexane Homocyclic compounds example : triplebond Homocyclic compounds example : cyclohexane

Aromatic homocyclic compounds

Organic compounds containing one or more benzene rings and their functionalized derivatives are called aromatic compounds.

Aromatic compounds exhibit resonance property .

Aromatic compounds are usually called benzenoid compounds since they resemble benzene in almost all of their properties.

There are ,however, examples of aromatic compounds which do not contain a benzene ring but instead contain other highly unsaturated ring and are known as non-benzenoids.

Based on the number of benzene rings present in molecule, they are further classified as monocyclic (one benzene ring), bicyclic (two rings), tricyclic (three rings) aromatic compounds etc.
