Cycloheptatrienyl frost circle

WebJan 28, 2016 · When you try to put 4n (or 4n+4) electrons into the ring as in cycloheptatrienyl anion, you have filled and empty states at the same energy level; … WebThe cycloheptatrienyl anion has 8 electrons which translates as 4n electrons, not the 4n+2 as implied by Huckel. If you are about to construct the MOs for both cycles, you'll find that putting 4n electrons will rise in a diradical molecule, not stable as it already sounds. A quick trick for doing that is using Frost's circle.
