Benzene Chemical Properties,Uses,Production
Definition
ChEBI: Benzene is a six-carbon aromatic annulene in which each carbon atom donates one of its two 2p electrons into a delocalised pi system. A toxic, flammable liquid byproduct of coal distillation, it is used as an industrial solvent. Benzene is a carcinogen that also damages bone marrow and the central nervous system. It has a role as a non-polar solvent, a carcinogenic agent and an environmental contaminant. It is an aromatic annulene, a volatile organic compound and a member of benzenes.
