Talk:Elimination reaction

Is this true?
I have a problem with the claim that "In most organic elimination reactions, hydrogens are lost..." I am going to change it to "In most organic elimination reactions, at least one hydrogen is lost..." I believe it is more accurate and I believe it helps to avoid the obvious question: "Most" in what context? Most known? Most by frequency? Most by commercial volume (or dollar value)? Since it is not clear to me that we even know what the "most" common elimination reaction is in the Universe, the term needs a context, but it seems too pedantic to include here.71.31.152.220 (talk) 21:18, 25 August 2012 (UTC)

The E1 reaction given is false. The reaction is done in basic conditions, so a carbocation cannot form. While it is a correct E1 mechanism, the E1 mechanism for that particular reaction is not correct, and is therefore misleading. The same reaction can proceed in ethanol with heat and without base by an E1 mechanism. See pages 382-391 of Organic Chemistry, Fourth Edition, by G. Marc Loudon for further discussion. — Preceding unsigned comment added by 128.112.120.98 (talk) 00:50, 21 April 2013 (UTC)

Correct me if I'm wrong but the E2 reaction states "Typically undergone by primary or secondary substituted alkyl halides". While this does apply to SN2 doesn't E2 also follow E1 in that tertiary and secondary are the better substrates? Changed the information requarding E2. 173.247.192.183 (talk) 10:17, 25 October 2013 (UTC)

Proposed merge with Dehydrohalogenation
This article only covers the E2 mechanism, but as the "opposite transformation [of] hydrohalogenation", E1 is at least as appropriate. And there's nothing here that is specific to dehydrohalogenation among various leaving groups. Instead, elimination reaction already covers what is here, including more discussion of the relationships among geometry and competing reactions, which are key details related to the topic and also popular information for undergrad-level students who probably are a major set of readers interested in this reaction.

 * oppose: Category:Elimination reactions has about 20 entries, starting from organic reaction all sub-articles have a certain logic to it. Merging articles will not help, expanding existing articles will help V8rik (talk) 20:03, 11 August 2015 (UTC)

also known as beta elimination?
is 1,2-elimination widely also known as "beta elimination"? i am reading this from a textbook (Organic Chemistry by Klein), which states that it 1,2-elimination is also known as beta elimination. 173.3.44.91 (talk) 21:12, 27 May 2022 (UTC)
