Talk:Lewis acids and bases

message: It appears to me that recent (Aug 2011) edits of this page have been rather self-serving and possibly not appropriate. I for one would like an explanation from FrozenMan as to what exactly is the reference for such ideas as "s-homo" and "lobe-HOMO" Lewis bases. As a chemistry educator and author I have never heard of such terms, and statements such as "There are generally thought to be four types of Lewis Bases and six types of Lewis Acids..." just doesn't ring a bell with me at all. Where is this coming from? Can we have a reference, please, that is not published by the author himself? The only references I can find are to a self-published (i.e. not peer reviewed?) book by Mark Leach entitled "Lewis Acid/Base Reaction Chemistry" reviewed in the Journal of Chemical Education -- http://pubs.acs.org/doi/pdf/10.1021/ed078p166. The three figures added (I am guessing) are from this book and do not by a long shot refer to anything that is "generally accepted." 
As it is, I do not feel comfortable sending my students to this far too complicated description of Lewis acids and bases, and I will move to strike this section in the near future, depending upon the response to my questions. Hansonrstolaf (talk) 22:04, 15 September 2011 (UTC)
thread_title: Idiosyncratic Editing?

message: It should be mentioned that all Bronsted-Lowery acids and bases ("normal" as the article calls them) are also Lewis acids and bases (though not all Lewis acids and Bronsted-Lowery acids).

thread_title: Bronsted-Lowry

message: After reading through the article, I do not see where the POV issue is. I would like someone to show me where the offending text lies--or better yet, fix the alleged problem.  Otherwise, I'm going to remove the POV tag. toll_booth (talk) 16:53, 27 July 2008 (UTC)
thread_title:  NPOV?? 

message: I noticed that the Brønsted–Lowry acid/base page is named a little differently. Maybe it would be better to change the name of one or the other to make them match? That would mean changing this one to "Lewis acid-base theory" or changing the other to "Brønsted–Lowry acids and bases" EricWesBrown (talk) 03:32, 2 July 2010 (UTC)

I found that picture while searching Google Images...since the first picture in this article needs a reference, would that link qualify as a reference to the picture included in the article?  — Preceding unsigned comment added by Andise1 (talk • contribs) 02:07, 4 January 2012 (UTC)

message: The direction of the arrow is from the Lewis base toward the Lewis acid.
Me3B←NH3
:Me3B  +  :NH3   →   Me3B:NH3
The sentence does not accurately describe the second "equation", only the first. What gives? 84.227.252.224 (talk) 08:56, 14 October 2014 (UTC)
replies: text: The arrow in the second is a normal reaction arrow (reactants on left, products on right); the surrounding text notes that it's the pair of dots that's the actual bond on both sides of the equation. The text you quoted is solely about the first complex itself (not a reaction). I overhauled the wording; let me know if it's self-consistent and clear/correct now.

thread_title:  Contradictory 

message: The article's information comes form cited textbooks and reference books written in the late 90's and the early 2000's. The sources are neutral. A comparison between Lewis A&B and Brønsted-Lowry is drawn, and a link is provided to the Brønsted-Lowry page.
All the links I clicked on were working and there was no detected plagiarism: no phrases sounded too similar or close together to raise any red flags.

thread_title:  Critique on Lewis acids and bases 

message: Can someone please add a clarification to the article for what Me stands for (as used in things like Me3B←NH3)?

replies: text: Hi Hops Splurt Ive not clarified Me But i've clarified what Me3B is by adding a link to its corresponding Wiki Page. --Newtdog402 (talk) 16:23, 17 February 2018 (UTC)
replies: text: Aha. Trimethylborane, with the Me standing for Methyl. Thanks for the update. --Hops Splurt (talk) 16:56, 26 February 2018 (UTC)
thread_title:  Please clarify "Me" 

message: Hello.
I think it would be good to add a paragraph about the difference between Lewis acid and oxydant (or between Lewis base and reducer). 
I'd do it, but when I think of it I'm not sure if this difference actually exists. 
It's often said that a Lewis acid-base reaction doesn't modify the oxidation state of the involved species, and involves covalent bonding / electron doublets (as opposed to redox reactions, where an electron is transferred, modifying the oxidation state and involving ionic bonding). 
But the oxidation state is just a modelling concept. So is the distinction between ionic and covalent bonding: AFAIK, at the fundamental level, there's no such thing as ionic vs. covalent bonding. This distinction is a convenient way to approach the behaviour of species, sometimes by attributing them a charge, sometimes by considering that the charge is shared. 
This leads me to the idea that the distinction between redox and Lewis acid-base is purely a modelling thing, not a fundamental/physical difference.
I'd like to know if I missed something before writing on it.  — Preceding unsigned comment added by 87.86.104.114 (talk) 13:10, 26 June 2022 (UTC)
