Ethylene oxide (oxirane) as shown by the chemical structure below is an important molecule used as a precursor to several other compounds. Instead of having two carbon atoms and one oxygen atom in a row, the three atoms form a ring. It was used in World War I to produce the coolant ethylene glycol and for the production of mustard gas (a chemical weapon). How does the structure of ethylene oxide differ from the structure of ethanol?
