## organic chemistry – What is the justification for Hückel’s rule?

The Question : 27 people think this question is useful I know that experimentally, the rule has been verified but I am having trouble understanding why it works. I see no reason why equivalent cyclic structures can undergo resonance and be just as stable. Any clarification would be nice. The Question Comments : Look at

## organic chemistry – Are graphite and hexagonal boron nitride aromatic

The Question : 29 people think this question is useful Are graphite and hexagonal boron nitride aromatic? Graphite has a planar network of 6-membered rings with each carbon connected to three other carbons. Since the valency of carbon is not satisfied, there will be some $\pi$-bonds. Can graphite act like an aromatic system? Can I

## organic chemistry – Is buckminsterfullerene aromatic?

The Question : 45 people think this question is useful According to Wikipedia, The $\ce{C60}$ molecule is extremely stable,[26] withstanding high temperatures and high pressures. The exposed surface of the structure can selectively react with other species while maintaining the spherical geometry.[27] Atoms and small molecules can be trapped within the molecule without reacting.
