WebEpoxide. In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen. This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers. They are produced on a large scale for many applications. WebFor example, the IUPAC name for ethyl methyl ether would be methoxyethane. In cyclic ethers, the stem of the compound is known as a oxacycloalkane. The "oxa" is an indicator of the replacement of the carbon by an oxygen in the ring. An example is oxacyclopentane, a five-membered ring in which there are four carbon atoms and one oxygen atom.
