==Cycloethane==
A google search of "cycloethane" gives a lot of questions (more questions than answers).  I did my due diligence and found a respectable source for this rare/controversial term.  I updated this page with info about this term.  I did NOT put this in the headline... in fact it appeared near the END of the page!  I also included objections to this term BEFORE the justification.  But almost immediately (within 10 minutes) after posting, my edit was reversed by *classified*.

I posted this edit with a verifiable source.  I also included objections AND justifications in my edit to provide a fair-and-balanced view of the term "cycloethane".

Yet my edit was almost immediately retracted.  This isn't how Wikipedia should work, IMHO.

Sure, if I was just giving my personal opinion, or if I was just giving the "google" opinion then this would be understandable.

But if I post an edit with a reliable/verifiable source, shouldn't this be AT LEAST open for debate... instead of immediate deletion?

Because my original post was deleted, I can't be 100% sure, but I believe my edit was approximately:
    "Ethylene is rarely (and controversially) named 'cycloethane'.  It is controversial because... It is justified because..."
    [with reference to "Basic Principles of Organic Chemistry" (second edition, page 483, ISBN 0-8053-8329-8)]

For the love of God, what was wrong with my edit?  Except for being unpopular??  Can we talk about this?  <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Hydradix|Hydradix]] ([[User talk:Hydradix#top|talk]] • [[Special:Contributions/Hydradix|contribs]]) 21:51, 2 May 2018 (UTC)</small> <!--Autosigned by SineBot-->

== Dandilions ==

Are you sure the stuff that [[dandilions]] release (ethylene) is the same substance that can be found from crude oil? [[User:Qwertyxp2000|'''Q'''wertyxp2000]] ([[User talk:Qwertyxp2000|talk]]) 05:07, 15 May 2015 (UTC)

== ethylene synthesis in plants ==

"Ethylene biosynthesis can be induced by endogenous or exogenous ethylene."
this sentence seems to be flawed, as it means effectively that ethylene production in a plant will be triggered by the presence of ethylene (either produced by the same plant, or coming from somewhere else). so it means once there is ethylene present there will be more of it produced, but this fails to account for what started the process to start with and also suggests that it is a self-inducing chain reaction while the same is not said by the previous - more detailed - part of the desription of the process. please remove and/or make more clear this sentence.[[Special:Contributions/80.98.114.70|80.98.114.70]] ([[User talk:80.98.114.70|talk]]) 12:41, 2 April 2016 (UTC).

==Assessment comment==
{{Substituted comment|length=4201|lastedit=20070302220720|comment=The following suggestions were generated by a semi-automatic [[User:AndyZ/peerreviewer|javascript program]], and might not be applicable for the article in question.
*Please expand the lead to conform with guidelines at [[Wikipedia:Lead]]. The article should have an appropriate number of paragraphs as is shown on [[WP:LEAD]], and should adequately summarize the article.<sup>[[User:AndyZ/G#lead|[?]]]</sup>
*Per [[Wikipedia:Only make links that are relevant to the context|Wikipedia:Context]] and [[Wikipedia:Manual of Style (dates and numbers)|Wikipedia:Manual of Style (dates)]], months and days of the week generally should not be linked. Years, decades, and centuries can be linked if they provide [[WP:CONTEXT|context]] for the article.<sup>[[User:AndyZ/G#contxt|[?]]]</sup>
*Per [[Wikipedia:Manual of Style (dates and numbers)#Units of measurement|Wikipedia:Manual of Style (numbers)]], there should be a non-breaking space - <code>&amp;nbsp;</code> between a number and the unit of measurement. For example, instead of ''100 mL'', use ''100&nbsp;mL'', which when you are editing the page, should look like: <tt>100&amp;nbsp;mL</tt>.<sup>[[User:AndyZ/G#nbsp|[?]]]</sup>
*Per [[Wikipedia:Manual of Style (dates and numbers)#Units of measurement|Wikipedia:Manual of Style (numbers)]], please spell out source units of measurements in text; for example, ''the Moon is 380,000 kilometres (240,000 mi) from Earth''.<sup>[[User:AndyZ/G#spellnum|[?]]]</sup> Specifically, an example is 100 mL.
*Per [[Wikipedia:Only make links that are relevant to the context|Wikipedia:Context]] and [[Wikipedia:Build the web]], years with full dates should be linked; for example, link [[January 15]], [[2006]].<sup>[[User:AndyZ/G#linkdate|[?]]]</sup>
*Per [[Wikipedia:Manual of Style (headings)]], headings generally should not repeat the title of the article. For example, if the article was [[Ferdinand Magellan]], instead of using the heading ''<nowiki>==Magellan's journey==</nowiki>'', use ''<nowiki>==Journey==</nowiki>''.<sup>[[User:AndyZ/G#headingre|[?]]]</sup>
*Generally, trivia sections are looked down upon; please either remove the trivia section or incorporate any important facts into the rest of the article.<sup>[[User:AndyZ/G#trivia|[?]]]</sup>
*There are a few occurrences of [[weasel word]]s in this article- please observe [[WP:AWT]]. Certain phrases should specify exactly who supports, considers, believes, etc., such a view.
**''it has been''
**''is considered''
**''are considered''
**might be weasel words, and should be provided with proper [[WP:FOOTNOTE|citations]] (if they already do, or are not weasel terms, please <s>strike</s> this comment).<sup>[[User:AndyZ/G#awt|[?]]]</sup> <!--This javascript cannot determine if a citation is provided; if all weasel terms are covered by citations, please strike this-->
*Please make the spelling of English words consistent with either [[American and British English spelling differences|American or British spelling]], depending upon the subject of the article. Examples include: ''behaviour'' (B) (American: ''behavior''), ''neighbor'' (A) (British: ''neighbour''), ''ization'' (A) (British: ''isation''), ''hydrolyse'' (B) (American: ''hydrolyze''), ''signaling'' (A) (British: ''signalling''), ''sulfur'' (A) (British: ''sulphur'').
*Avoid using contractions like (outside of quotations): ''wasn't''.
*As done in [[WP:FOOTNOTE]], footnotes usually are located right after a punctuation mark (as recommended by the [[The Chicago Manual of Style|CMS]], but not mandatory), such that there is no space in between. For example, ''the sun is larger than the moon [2].'' is usually written as ''the sun is larger than the moon.[2]''<sup>[[User:AndyZ/G#footspace|[?]]]</sup>

== Why is Ethene not the main entry? ==

It's a long time since I studied chemistry, but I'm surprised that Ethene redirects to Ethylene, rather than the other way around. Ethene has been the IUPAC name for this compound for a long time now and while ethylene may be in more common use, I cannot see that being a good argument for not listing a chemical compound under its official name.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/203.173.154.136|203.173.154.136]] ([[User talk:203.173.154.136#top|talk]]) 02:09, 17 October 2018 (UTC)</small> <!--Autosigned by SineBot-->
:Wikipedia titles articles by their common name (see [[WP:COMMONNAME]]).  For this reason many (most?) articles about chemical compounds are not titled using IUPAC nomenclature.  [[User:ChemNerd|ChemNerd]] ([[User talk:ChemNerd|talk]]) 16:08, 30 October 2018 (UTC)
==Split proposal==
The role of ethylene as a plant hormone is a big area and pretty different from the usual chemical/petrochemical aspects. Also it looks like increasing amount of primary literature is creeping into article.  So if we split, readers might find the info more useful.  The parent article would of course retain brief mention of the hormone aspect.--[[User:Smokefoot|Smokefoot]] ([[User talk:Smokefoot|talk]]) 16:40, 30 April 2020 (UTC)
