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: |

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' |

I'm pretty sure that any carbonyl group adjacent to an N, NH or NH<sub>2</sub> 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." |

== 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.--[[User:Smokefoot|Smokefoot]] 04:52, 20 February 2006 (UTC) |

also the amide forming reaction from acid chloride and an alkyl amine is incorrect as one CH2 was lost.--[[User:Smokefoot|Smokefoot]] 00:58, 22 February 2006 (UTC) |
|||
==Properties as bases== |
|||
the [[Amine#Properties as bases|article]] says that:<br> |
|||
The nitrogen atom features a [[lone electron pair]] that can bind H<sup>+</sup> to form an [[ammonium ion]] R<sub>3</sub>NH<sup>+</sup>. |
|||
The wiki page about [[ammonium ion]] says that its formula is NH<sub>4</sub><sup>+</sup>. <br> |
|||
Could somebody correct this ?<br> |
|||
What is the name of R<sub>3</sub>NH<sup>+</sup> ? |
|||
--[[User:Colonna|Colonna]] 13:36, 25 April 2007 (UTC) |
|||
:"Ammonium" can refer either to NH<sub>4</sub><sup>+</sup> itself or more generally to compounds with four groups attached to a positively charged nitrogen - R<sub>4</sub>N<sup>+</sup>. NH<sub>4</sub><sup>+</sup> is just the case where the four R groups are hydrogens and R<sub>3</sub>NH<sup>+</sup> is the case where only one is. --[[User:Edgar181|Ed]] ([[User talk:Edgar181|Edgar181]]) 14:03, 25 April 2007 (UTC) |

- We have this article: Metal amides which describes some compounds with R2N- ligands. In most cases, R = alkyl or aryl. Wikipedia lacks many editors with strong interests in main group chemistry. --Smokefoot (talk) 21:54, 22 September 2023 (UTC)
