I don't see any oxygen in the structure diagram. Am I missing something? The image is

which is identical to

Hmmm... I clicked on Reload and it appeared...
[edit] Duplicate page
I notice that there is another (and IMHO much inferior) page on this compound at epoxyethane. I would like to turn that page into a simple redirect to this page. Any comments? Walkerma 06:10, 19 Mar 2005 (UTC)
[edit] IUPAC name
The article states that the IUPAC name of ethylene oxide is "1,2-epoxyethane". I don't think the numbers are needed in this case, since there is no ambiguity in the name "epoxyethane", and according to the naming guidelines, position numbers should not be used when not necessary. 193.217.163.93 14:26, 3 October 2006 (UTC)
[edit] Old chembox
I'm moving the old chemical infobox here, as I've replaced it with a chembox new.
