Dear Godre,


 


Hückel’s Rule: The (4n + 2) p Electron Rule


For  monocyclic planar compounds in which each atom has a p orbital (as in benzene) Hückel showed that compounds with (4n + 2) p electrons, where n = 0, 1, 2, 3 etc, would have closed shells of delocalised p electrons and should show exceptional stability (high resonance energy º “aromatic”).


i.e. planar monocycles with 2, 6, 10, 14….delocalised p electrons should be “aromatic”.


i.e. p electrons are delocalised over the entire ring and the compound is thereby stabilised by the delocalisation.
