aromatic hydrocarbons

Aromatic Hydrocarbons Structure of Benzene: - simplest aromatic hydrocarbon is benzene, C6H6 - sweetish-smelling liquid first isolated in 1825 by Michael Faraday from the oily residue that had collected in gas lines - this formula has so few hydrogen atoms for the number of carbon atoms that an unsaturated molecule would seem likely - Kekule proposed a ring structure involving alternating single and double bonds, years later Dewar and Ladenburg proposed very different molecules for …

…almost as good as a solvent as benzene and is comparatively less harmful - it is possible to have compounds containing connected benzene rings - Naphthalene, a compound in which two benzene rings share a common side, is used as a moth repellent - The carcinogenic compound 3,4-benzopyrene is produced in significant quantities in any burning or charring process, thus both cigarette smoke and char broiled foods contain this hazardous chemical ------------------------------------------------------------------------ **Bibliography** no bibliography
