AROMATIC HYDROCARBON
- Aromatic hydrocarbons are also called arenes due to their pleasant odor.
- Aromatic compounds are highly unsaturated and most of them contain a benzene ring.
- Benzene ring is a hexagonal ring with alternate double bonds.
- Aromatic compounds often retain the unsaturation of the benzene ring in reactions.
- Some aromatic hydrocarbons may not contain a benzene ring but have other highly unsaturated rings.
- Aromatic compounds that contain a benzene ring are known as benzenoids.
- Aromatic compounds that do not contain a benzene ring are known as non-benzenoids.
