[edit] anoroganic aromatic compounds!
There are anoroganic compounds that are aromatic, too, e.g. B3N3H6. —The preceding unsigned comment was added by 141.52.232.84 (talk) 07:33, 12 June 2003 (UTC)
[edit] Misc Comment
Only circular arrangements wich contains (4*N)+2 (N=1->infinite) free electrons are aromatic. As example, C6H6 (benzene) is aromatic because it has 6 free electrons (4*1+2), while C8H8 is not aromatic (8 != (4*N)+2)... —The preceding unsigned comment was added by 193.190.211.20 (talk) 12:04, 12 December 2003 (UTC)
[edit] Article redundancy?
Some of the information here is shared with aromatic hydrocarbon, and that article has some extra stuff that should perhaps be here. How should the topic be divided up, really? I'm thinking there ought to be one major article, probably called "Chemical Aromaticity" or something like that. The aromatic hydrocarbon article could then be much shorter, referring to the aromaticity article for all the general information about the phenomenon. ACW 01:24, 7 Nov 2004 (UTC)
I tried to spot out the main needs for aromaticity as depicted by textbooks with a numbered list. Althought maybe it is quite redundant, i think it should be pointed out more clearly what are these requirements. I'm not satisfied, but i prefer to leave it to be fixed by someone else in order to gain a more clear language for this article. Needless to say, but feel free to revert it completely. --munehiro 15:19, 4 Apr 2005 (UTC)
[edit] Why 'aromatic'?
One of the first things anyone just learning about aromatic compounds is going to want to know is why they're called that - how the technical usage fits in with and differs from the normal English usage. I'm thinking that (rather like organic compounds) it's because the first few aromatic compounds identified were indeed aromatic in the sense of smelly, even though this is neither necessary nor sufficient for chemical aromaticity, but I couldn't swear to this. Anyone? --Oolong 11:53, 4 November 2005 (UTC)
- This was my first question as well, in case any chemical history buffs are looking for a reason to add a section to the article. --Robertb-dc 22:15, 6 March 2006 (UTC)

- This is indeed the origin of the term, according to the intro orgo textbooks I have on hand (by Wade and by Streitwieser/Heathcock/Kosower) so I added it to the article. DMacks 22:41, 6 March 2006 (UTC)
[edit] Benzyne
i found that benzyne C6H4 is also aromatic but it does not follow huckle rule i.e. (4n+2)π electrons .why —The preceding unsigned comment was added by 61.1.6.181 (talk • contribs).
- The end of the Hückel's rule page notes:
-
- Aromaticity - A much more thorough explanation of what makes a molecule aromatic. Huckel's rule is a simple rule that sometimes fails.
- Might want to follow that link for more detailed information. In particular, consider the molecular orbitals on the two atoms involved in the "alkyne-like" bond. How are the two p orbitals on each oriented, and what effect that might have on whether both π bonds are actually involved in the aromatic system. DMacks 08:40, 27 November 2006 (UTC)
Benzyne is aromatic and follows the Huckel rule. The unpaired electrons are in sp2-orbitals in the molecule plane, and do not participate in the pi-system. Huckel's rule is very reliable. LinguisticDemographer 14:49, 28 February 2007 (UTC)
