Talk:Dicoronylene

Ball-and-stick picture is incorrect
It is not possible to draw a resonance structure of dicoronylene with a double bond bridging the two coronene moieties. The bonds connecting the two moieties should be drawn as pure single bonds.

(Proof: any such resonance structure must either have one or both bridging bonds written as double. If only one bridging bond is double, then each coronene moiety must contain 11 1/2 pi bonds - impossible. If both bridging bonds are written as double, all of the double bonds are locked as horizontal and the two ends are left hanging.) Magic9mushroom (talk) 06:58, 15 November 2019 (UTC)
