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,
813:
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
808:
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
613:
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
385:
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
797:
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
936:
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
512:
A cursory examination of the use of words like "aroma", "aromatic", "aromatic compound", in the 19th century strongly suggests the culprit is rooted in
Benzoin, having a prototypically spicy aroma, and whence benzoic acid was extracted, whence... benzene was synthesized, all of which having
830:
However, sometimes, a
Knowledge 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."
518:
Common are references to
Benzoin as among the aromatic gums, and odor-wise benzene has not fallen far from the Benzoin tree. So, over the course of ~70 years, it's not hard to see chemists simply associating anything with benzene rings as 'aromatic', regardless of odor.

is a highly useful educational link from a top notch source. It's a reliable source in and of itself and has information not in the article. And the website isn't selling anything, so it doesn't seem like spam to me. Let's include it.
793:
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.
398:
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

distinctly pleasant fragrance (benzoic acid has to age a bit, but in the 19th century, it would typically sit around for a while in the apothecary's jar...), some more some less, and even toluene and the xylenes, if on the sharp side.
374:, 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

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.--

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.

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
1114:
686:
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.
430:
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.

Knowledge'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.
