Compounds that contain at least one 6-carbon ring; often important components of oils.

Organic compounds containing Carbon and Hydrogen in the form of an unsaturated, usually hexagonal ring structure. The compounds can be single ring, or double, triple, or multiple fused rings.

A major group of unsaturated Cyclic Hydrocarbons containing two or more rings. The vast number of compounds of this important group, derived chiefly from Petroleum and Coal Tar, are rather highly reac [..]

Hydrocarbon compounds in which the carbon atoms are connected by a ring structure that is planar and joined by sigma and pie bonds between the carbon atoms. An example of an aromatic compound is benze [..]

The group of hydrocarbon products which include benzene, toluene, etc. and provide feedstocks for many of the main petrochemical processes asa well as high octane rating gasoline blends. So-called fro [..]

Hydrocarbon characterized by unsaturated ring structures of the carbon atoms. Commercial petroleum aromatics are benzene, toluene, and xylenes.
