Epoxides are a type of organic compound which are characterized by a three-membered ring containing an oxygen atom. This unique structure gives epoxides a distinct set of properties and reactions, making them useful in a variety of applications. However, if you are looking to expand your vocabulary, there are a number of other terms you could use to describe these compounds. Some common synonyms for epoxide include oxirane, ethylene oxide, and epoxyethane. Each of these terms refers to the same basic structure, but may be more appropriate in certain contexts depending on the intended audience or level of technical detail.
