in which condn....this rule is valid[huckle's rule]?
Hi ,
Huckle rule estimates whether a planar ring molecule will have aromatic properties.A cyclic ring molecule follows rule when the number of its π-electrons equals 4n+2 where n is zero or any positive integer, although clearcut examples are really only established for values of n = 0 up to about n = 6.[5] Hückel's rule was originally based on calculations using the Hückel method, although it can also be justified by considering a particle in a ring system, by the LCAO method and by the Pariser–Parr–Pople method.Aromatic compounds are more stable than theoretically predicted by alkene hydrogenation data; the "extra" stability is due to the delocalized cloud of electrons, called resonance energy. Criteria for simple aromatics are: 1. follow Huckel's rule, having 4n+2 electrons in the delocalized p-orbital cloud; 2. be able to be planar and are cyclic; 3. every atom in the circle is able to participate in delocalizing the electrons by having a p-orbital or an unshared pair of electrons.
