Web26 sep. 2014 · Hückel's rule (or the 4 n + 2 rule) suggests that systems with 4 n + 2 π electrons will be stabilized (aromatic), while systems with 4 n π electrons will be destabilized (antiaromatic). It was written with planar, monocyclic, π-systems in mind. Web17 aug. 2024 · Benzene is aromatic and especially stable because it contains 6 electrons. Cyclobutadiene is antiaromatic and especially unstable because it contains 4 electrons.
