So is this the only molecule with a d (yes, 1,3,5-cyclohexatriyne)? 80.98.179.160 (talk) 15:22, 19 March 2018 (UTC)
 * Leaving aside the question of what "doubly aromatic" would even mean, it's not even aromatic in the first place. Hückel's rule tells us that a planar ring molecule must have a singly even number of π-electrons to be aromatic (i.e. even but not divisible by 4): benzene has six (three pi bonds) but benzotriyne has twelve (six pi bonds).

 * So a new question: why would cyclohexahexaene be only metastable? 2 X=X bonds should have more binding energy tban 1 triple + 1 single bond. Alfa-ketosav (talk) 08:15, 21 August 2018 (UTC)
