message: 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)
thread_title:  anoroganic aromatic compounds! 

message: 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)
thread_title:  Misc Comment 

message: 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.

thread_title:  Are terpenes aromatic 

message: 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)
thread_title:  Benzyne 

message: One thing I've always been curious about is how do you determine if larger ring systems are aromatic or not. I'm talking about multiring systems like coronene and heme, and joined ring systems like stilbene. I'm also mystified in how one factors in any exocyclic, conjugated double bonds into the analysis, as those in benzoic acid, benzophenone and anthracyclines. -- 22:11, 30 July 2007 (UTC)

message: It seems unclear what double arrow diagram the first sentence of the theory section is talking about. Aaronatwpi (talk)
:It's talking about the one used in the diagram at the beginning of the article, which is indeed not obvious:( I wonder if the diagrams used to be together here and/or if maybe they should be together (either here or in the lead)? I added some links to the discussion of the more general phenomenon of resonance, which should begin to solve the problem here. DMacks (talk) 03:25, 7 February 2008 (UTC)

message: Wikipedia's guidelines say the lead should be discrete and nontechnical. Yet the opening paragraph 1) has seven hyperlinks, and 2) it's meaningless to the lay person.
The lead should have a dictionary-like definition, but be more comprehensive.  By definition, an encyclopedia is an overview, not a publication of, or for specialization.  Only when "overview" is met should it possibly continue deeper.
One reason hyperlinks in the lead should try to be avoided is if not, finding a general/overview/lay meaning might be impossible as a person is linked from one hyperlink to another; forever.  For example, I got here from the lead in "gasoline."  Therefore I must become an organic chemist to have a feel for what gasoline and any "aromatic compound" is!? Or here, is it: "Average Joe has no business being interested in this?"
quote: 
"Aromatic compound" redirects here. For meanings related to odor, see aroma compound.  
In organic chemistry, the structures of some rings of atoms are unexpectedly stable. Aromaticity is a chemical property in which a conjugated ring of unsaturated bonds, lone pairs, or empty orbitals exhibit a stabilization stronger than would be expected by the stabilization of conjugation alone. It can also be considered a manifestation of cyclic delocalization and of resonance.
With so much jargon and so forth in the paragraph, the prudent lay person might wonder if every word is jargon, thus undecypherable and meaningless. For example, "unexpectedly?"  Unexpected if counting valence rings, or cyclic delocalization, or what? 
Guessing wildly, I wonder if the first sentence could be rewritten as: "To overgeneralize, an aromatic compound is unusually stable or inert?"  I don't know.  However, it has been written; Sometimes a little inaccuracy saves a great deal of obscurity.  I'm seeking a general concept, not the requirements of a chemist.
from: http://en.wikipedia.org/wiki/Wikipedia_is_not_a_dictionary#Fixing_bad_articles.2Fstubs 
 However, sometimes, a Wikipedia article (particularly stubs) will be badly written. Its introduction will say something such as "Dog is a term for an animal with the binomial name Canis lupus." ....  Simply replace the cumbersome phrasings ... with ...  "A dog is a domesticated canine." 
While expertise in a field is no indicator of communication ability, certainly it does not preclude it? 
:"Communication is a process whereby meaning is defined and shared between living organisms. Communication requires a sender, a message, and an intended recipient," 
:"The communication process is complete once the receiver has understood the sender."

thread_title:  The lead is too technical, & too many hyperlinks. 

message: In The structure of the benzene ring, the paragraph beginning Here, Armstrong is describing at least four modern concepts strikes me as speculative. Just because Armstrong's prose can be identified poetically or metaphorically with modern technical concepts does not mean he really was stumbling towards Bethlehem. It is an interesting thesis. It might be true. But it should be investigated in depth somewhere by someone, and declared in a publication, perhaps achieve a scholarly consensus, before being presented here. 84.227.252.224 (talk) 20:02, 14 October 2014 (UTC)
thread_title:  OR paragraph -- speculative 

message: It is said:"Thus, there are not enough electrons to form double bonds on all the carbon atoms, but the "extra" electrons strengthen all of the bonds on the ring equally. The resulting molecular orbital is considered to have π symmetry.". Six interacting p atomic orbitals give rise to 6 molecular orbital, not one. Three of them are bonding (one more so than the remaining two) and are entered by the six electrons. The figure just below shows only the first of those three molecular orbitals.--5.95.105.48 (talk) 19:22, 9 November 2020 (UTC)
