WebNov 16, 2015 · The solubility of benzene in water is 1.79 g/L (about 0.02 mol/L) at 15 °C. So benzene has some solubility in water. But many chemists set the high/low solubility cut-off point at about 0.10 mol/L. By that definition, benzene is insoluble in water. The question then is, "Why is benzene relatively insoluble in water?" WebAug 29, 2014 · Description. Ethylene oxide is also called oxirane. It is a cyclic ether that is a colorless flammable gas at room temperature, with a faintly sweet odor. It is the simplest epoxide known. Because of its special molecular structure, ethylene oxide easily participates in addition reactions; e.g., opening its ring and thus easily polymerizing.
