External links modified
Hello fellow Wikipedians,

I have just added archive links to 1 one external link on 2-Butene. Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:
 * Added archive http://web.archive.org/web/20091209074235/http://www.inchem.org:80/ to http://www.inchem.org

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at ).

Cheers.—cyberbot II  Talk to my owner :Online 04:24, 21 March 2016 (UTC)
