Epoxides are a type of organic compound characterized by a three-membered cyclic ether structure. This means they contain an oxygen atom bonded to two carbon atoms, forming a triangle shape. This unique structure makes epoxides highly reactive, allowing them to participate in various chemical reactions. They are commonly used in the production of plastics, adhesives, and coatings. One of the most well-known epoxides is ethylene oxide, which is used to sterilize medical equipment and produce antifreeze. Due to their reactivity, epoxides can also be transformed into other useful compounds, making them important in the field of organic chemistry.
