oksirengas
Oksirengas is a term used in chemistry to denote the oxirane ring, a three-membered cyclic ether that contains two carbon atoms and one oxygen atom. The simplest member of this class is ethylene oxide (also known as oxirane or ethene oxide), with the chemical formula C2H4O. The ring is small and highly strained, which gives oxiranes distinctive reactivity compared with other ethers. The IUPAC name for this structure is oxirane.
Reactivity and properties: The ring strain of about 27 kcal/mol makes oxiranes more reactive toward nucleophilic
Synthesis and occurrence: Epoxides (oxiranes) can be prepared by oxidizing alkenes with peracids (the Prilezhaev reaction)
Safety and handling: Epoxides are reactive and can be irritants or toxic. Ethylene oxide, in particular, is
