Category talk:Functional groups
'Functional group' and 'homologous series' are becoming confused. Many of the articles listed in this category are not functional groups but are homologous series. For example, Acid anhydride is not a functional group but a homologous series. It has a functional group; the carbonyl group, but in its itself it is not a functional group.
We need a category for homologous series. I am going about expanding the homologous series page right now. I am not to confident on making whole new categories so maybe someone else can do that.

- I don't think we should remove anhydride from the functional groups list. Obviously, in addition to the functional group category, we can include it in the homologous series category. Personally, I don't think 'Homologous series' deserves it's own category, but I am not the final authority on these matters. ~K 00:09, 22 Jun 2005 (UTC)
Why is urea here? It's not a functional group. Meconium 05:56, 28 May 2006 (UTC)
I think these pages would be better if we could differentiate between, functional groups, substituents and families of compounds. For example, methoxy is a substituent and maybe a functional group but not a family of compounds. lactones are a family of compounds and maybe a functional group but not a substituent Spookyrunner13 (talk) 00:58, 17 May 2010 (UTC)spookyrunner13
- I agree. I started a category called category:substituents. Please let me know if it is ok. --kupirijo (talk) 11:02, 21 November 2010 (UTC)
There is no page for the primary, secondary or tertiary ammonium cation functional groups
There is a page for Quaternary ammonium cations but not primary, secondary or tertiary. They contain R-R-R-NH+, R-R-NH2+ or R-NH3+.
These groups are very important both as intermediates and in salts or zwitterions. See the section Ammonium#Organic_ammonium_ions for more information.
A page on this type of group would be very useful :-)
