aromatic compound
a hydrocarbon containing one or more benzene rings that are characteristic of the benzene series of compounds
(Chem.), one of a large class of organic substances, as the oils of bitter almonds, wintergreen, and turpentine, the balsams, camphors, etc., many of which have an aromatic odor. They include many of the most important of the carbon compounds and may all be derived from the benzene group, C6H6. The term is extended also to many of their derivatives.
