WebBenzene is lipid soluble and highly volatile at room temperature. As such, benzene readily crosses the alveolar membranes and is taken up by circulating blood in pulmonary … WebStructure of Benzene. The structure of benzene was determined many years ago, by a chemist called Kekule. The structure consists of 6 carbon atoms in a hexagonal ring, with alternating single and double carbon-carbon bonds. This suggests that benzene should react in the same way that an unsaturated alkene does. However, this is not the case.
