WebHuckel Rule of Aromaticity (4n+2) Pi Electron Rule. Huckel's rule stated mathematically says that all planar aromatic compounds must have 4n+2 pi-electrons where n is a positive integer or zero (i.e. n= 0, 1, 2, 3…etc.). Aromatic compounds are comparatively stable due to the presence of resonance energy and delocalized electron clouds.
