Ethylene oxide - Wikipedia

Ethylene oxide is an organic compound with the formula C 2 H 4 O.It is a cyclic ether and the simplest epoxide: a three-meered ring consisting of one oxygen atom and two carbon atoms.Ethylene oxide is a colorless and flammable gas with a faintly sweet odor. Because it is a strained ring, ethylene oxide easily participates in a nuer of addition reactions that result in ring-opening.
