Non-aromaticity

I think quinones are aromatic. But in the article it is said that they are not aromatic. Can anyone explain?

Read aromaticity. The double bonds of quinone are localized. Icek 00:07, 29 March 2007 (UTC)

Huckles rule is a simple check for aromaticity, and drawing electron movement arrows helps as well -MKausch —Preceding unsigned comment added by 76.180.153.183 (talk) 05:37, 11 June 2008 (UTC)

Electron delocalization is not possible on the carbonyl carbons User:CountZepplin Sept 2008 —Preceding undated comment was added at 09:59, 11 September 2008 (UTC).

This page needs to be wikified slightly

This page could use a little help, especially considering the fact that introduction section is somewhat dense.RSido 21:13, 25 February 2007 (UTC)

Meta-quinone?

Shouldn't there be a meta-quinone with the formula C1(=O)CC(=O)C=C=C1 ? (but it would be quite unstable) Icek 00:07, 29 March 2007 (UTC)

They ARE Aromatic

Quinone are actually well-known for BEING AROMATIC. The double bonds are actually NOT localized. If you look at the Carbonyl carbons, you will realize that these carbons are SP2 hybridized AND each contain one pi electron in their p orbitals. (This electron contributes to the C=O bond.) If you count these two electrons + the 4 in the two double bonds, Quinone had 6 pi electrons, which IS a Huckel number! Hence...aromatic. —Preceding unsigned comment added by 98.217.65.10 (talk) 05:59, 10 February 2009 (UTC)

I replaced the intro, which was rather rough and possibly wrong, with the official IUPAC definition. IUPAC nicely sidesteps this issue of aromaticity, which probably needs a more thorough analysis using MO theory. Walkerma (talk) 16:15, 12 February 2009 (UTC)
