Benzene, also known as benzol, is an organic chemical compound with the formula C6H6. It is a colorless and flammable liquid with a sweet smell. Benzene molecules are a ring of six carbon atoms that are each bonded to one hydrogen atom. It is an aromatic compound, meaning the ring has alternating double bonds.
