Huckel's rule of aromaticity states that for aromaticity, a compound should becyclic (no sp3 atoms), planer and with a conjugated system of 4n+2 pi-electrons. Benzene is the most important and simplest example of this.

The property is common to all aromatic compounds and is referred to as aromaticity or aromatic character. The aromatic character of benzene is correlated to its structure, Aromaticity is due to extensive cyclic delocalization of p-electrons in planar ring structures

The three rules of aromaticity are useful in predicting whether a particular compound is aromatic or non-aromatic.

(1) Aromatic compounds are cyclic and planar (all atoms in ring are sp^2 hybridized.)

(2) Each atom in aromatic ring has a p-orbital. The p-orbitals must be parallel so that continuous overlap is possible around the ring

(3) The cyclic molecular orbital formed by overlap of p-orbitals must contain (4n+2) p electrons, where n integer 0, 1, 2, 3, etc.
