Why is this molecule anti-aromatic if it has 10 pi electrons, satisfying the 4n+2 rule of aromaticity? —Preceding unsigned comment added by 128.103.54.204 (talk) 18:09, 10 November 2010 (UTC)
 * Because of the fact that exterior bonds only have 8 pi electrons, satisfying the 4n rule of antiaromaticity. Alfa-ketosav (talk) 20:45, 9 November 2018 (UTC)
