Aromatic

Name:
Aromatic
Detailed information:
(arene).A major group of unsaturated cyclic hydrocarbons containing one or more rings, typified by benzene, which has a 6-carbon ring containing three double bonds. The vast number of compounds of this important group, derived chiefly from petroleum and coal tar, are rather highly reactive and chemically versatile. The name is due to the strong and not unpleasant odor characteristic of most substances of this nature. Certain 5-membered cyclic compounds such as the furan group (heterocyclic) are analogous to aromatic compounds.Note: The term “aromatic” is often used in the perfume and fragrance industries to describe essential oils that are not aromatic in the chemical sense.
