{wiki=Hückel's_rule}
Hückel's rule is a principle in organic chemistry that provides a criterion for the stability of cyclic, planar, and fully conjugated polyene systems. According to Hückel's rule, a cyclic compound will exhibit aromatic stability if it contains \\(4n + 2\\) π electrons in its conjugated system, where \\(n\\) is a non-negative integer (0, 1, 2, etc.).
