Benzene, the most widely recognized aromatic compound with six delocalized π electrons (4 n + 2, for n = 1). In organic chemistry, Hückel's rule predicts that a planar ring molecule will have aromatic properties if it has 4 n + 2 π electrons, where n is a non-negative integer. The quantum mechanical basis for its formulation ...
