Talk:Butene

I am curious whether the following isomers could be added for butene. We are forgetting to break the double bond, this would therefore include methylcyclopropane and cyclobutane. the initial page did mention these two molecules but neglected to leave the ene ending out of the molecule naming, therefore creating a discrepency in the amount of hydrogen atoms. Methylcyclopropane and cyclobutane both consist of 4-carbons and 8-hydrogens, thus they are isomers of butene.

 * In addition to the four isomers of butylene covered in this article, the following "similar" compounds were mentioned as not being covered by this article:
 * cyclobutane - C4H8 - an alkane
 * methylcyclopropane - C4H8 - an alkane
 * cyclobutene - C4H6 - an alkene
 * methylcyclobutene - C4H6 - an alkene
 * Actually there are 2 types: 1-methylcyclobutene and 3-methylcyclobutene

cyclobutene and methylcyclobutene are not isomers of butene as they do not have the same molecular formula (C4H8). The other molecules you have stated are indeed isomers of butene and should be added to the list. --:Sha'ashua! 18:35, 1 February 2014 (UTC)

I am wondering whether it would be a good idea to rename this page butene as this is the term mainly used in the text (and on this page as well) and butylene is a term that is falling out of use. Also it would be line with the articles on "pentene" and "propene".--AssegaiAli (talk) 21:06, 8 February 2008 (UTC)

No response so I have gone ahead and renamed the page.--AssegaiAli (talk) 22:50, 18 February 2008 (UTC)

IUPAC Names
I'm not very sure that the IUPAC names are correct shouldn't they be but-1-ene instead of 1-butene, etc.? — Preceding unsigned comment added by 175.142.171.100 (talk) 14:59, 8 May 2012 (UTC)


 * In my experience, American chemists tend to write 1-butene, while British chemists prefer but-1-ene. Not sure what the official IUPAC rule is. It may say both are acceptable. --Ben (talk) 15:45, 8 May 2012 (UTC)

I'm pretty sure the British method you speak of is the IUPAC method. Check this out: http://en.wikipedia.org/wiki/IUPAC_organic_nomenclature#Alkenes_and_Alkynes 175.142.171.100 (talk) 09:16, 19 May 2012 (UTC)

Actually, 1-butene was the correct IUPAC nomenclature in their 1979 version. By 1993, this had become but-1-ene. See http://www.acdlabs.com/iupac/nomenclature/. JSR (talk) 18:43, 18 June 2012 (UTC)

Should this be article be titled Butenes?
We are not discussing a single butene, but multiple butenes. Kirk Othmer discusses the topic as "Butylenes". JSR (talk) 15:56, 15 February 2017 (UTC)
