"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. " - Can ethers be rings

WebWe'll start off with the common way of naming ethers, which follows the pattern of first naming one of the alkyl groups attached to your oxygen and then naming the other aklyl group. And then, followed by the word "ether." Like that. So alkyl, alkyl, ether. Let's look at an example of common nomenclature. The study of heterocyclic chemistry focuses especially on unsaturated derivatives, and the preponderance of work and applications involves unstrained 5- and 6-membered rings. Included are pyridine, thiophene, pyrrole, and furan. Another large class of heterocycles refers to those fused to benzene rings. For example, the fused benzene derivatives of pyridine, thiophene, pyrrole, and furan are quinoline, benzothiophene, indole, and benzofuran, respectively. The fusi…
