Table of Kb values

Somebody, please set the table of Kb values right. I added some content, and then, extra values to support it (and messed up the format).

This page's content is so problematic that it likely should be pulled, and recast, only including information that can be entered with certainty, from reliable, verifiable sources. Web citing web IS NOT enough for a reliable encyclopedia entry. (This said, because I have found enough discrepancies, that I cannot recommend.)

Quaternary Amines

Should really add quaternary amines here.

a "quaternary amine" being ...?--Smokefoot 22:49, 19 February 2006 (UTC)[reply]

An amine with four bonds to carbon bearing a positive charge.RabidRabbit23 (talk) 09:34, 29 January 2011 (UTC)[reply]

Sentence problem

This sentence is giving me trouble, mostly b/c I'm not an organic chemist, but if it's confusing to me it's likely to be confusing to others. Anyway I hope someone could clarify and then update it in the article:

"However, if any of the carbons bonded to the nitrogen that is part of a carbonyl group, then the compound is considered an amide rather than an amine."

Does this mean -- if any of the carbons in the 'R' group are, in turn, part of a carbonyl group, then the whole deal is an 'amide' instead of an 'amine'

basically 'that is' is ambiguously referring to one of 'the nitrogen' or 'the carbons'

Thx.

I'm pretty sure that any carbonyl group adjacent to an N, NH or NH₂ makes it an amide. Perhaps:

"However, if any of the carbons bonded to the nitrogen are also part of a carbonyl group, then the compound is considered an amide rather than an amine." Anand 21:57, 19 February 2006 (UTC)[reply]

Drawing

Nice drawing for the nitrile and amide reductions by LAH, but you might revise the nitriles so that R-C-N are linear in the starting material.--Smokefoot 04:52, 20 February 2006 (UTC)[reply]

also the amide forming reaction from acid chloride and an alkyl amine is incorrect as one CH2 was lost.--Smokefoot 00:58, 22 February 2006 (UTC)[reply]

Properties as bases

the article says that:
The nitrogen atom features a lone electron pair that can bind H⁺ to form an ammonium ion R₃NH⁺. The wiki page about ammonium ion says that its formula is NH₄⁺.
Could somebody correct this ?
What is the name of R₃NH⁺ ? --Colonna 13:36, 25 April 2007 (UTC)[reply]

"Ammonium" can refer either to NH₄⁺ itself or more generally to compounds with four groups attached to a positively charged nitrogen - R₄N⁺. NH₄⁺ is just the case where the four R groups are hydrogens and R₃NH⁺ is the case where only one is. --Ed (Edgar181) 14:03, 25 April 2007 (UTC)[reply]

What's the correct pronunciation for "amine"?

206.240.25.247 (talk) 03:04, 17 February 2008 (UTC)[reply]

There are two different pronunciations in common use; see [1], which even has audio versions. --Itub (talk) 11:49, 18 February 2008 (UTC)[reply]

Classes of amine

Should cyclic nitrogen containing organics such as pyrroles be included as a class of amine? At least one of the molecular structures shown in pyrroles meets the definition given in the lead for an amine. If pyrroles are not amines, then that should be mentioned as it is likely many readers would think they are. Qemist (talk) 00:12, 2 May 2010 (UTC)[reply]

diagram labels

What is the dashed line? A hydrogen bond? Could someone label it as such? Or if it's labeled in a standardized fashion, at least inform the reader of the standard? —Preceding unsigned comment added by Blafreniere (talk • contribs) 07:03, 17 September 2010 (UTC)[reply]
