Title: Why is this molecule aromatic?
Post by: moomam on April 17, 2020, 07:33:34 PM

I believe a molecule is aromatic if it has 4n+2 π electrons. However, they state that the nitrogen's 2 p electrons are delocalized, so now the ring should have 8π electrons, and therefore should not be aromatic, right? And if a molecule isn't aromatic, will it have a ring current, given that it doesn't have the stable and flat structure of an aromatic?

Is nitrogen part of the ring?

aromaticity rules apply to cyclic, planar, fully conjugated systems only.
