A. Unsaturation
B. Cyclic structure
C. Presence of 4nπ electrons
D. Presence of 4n+2π electrons
¨ Presence of 4n+2π electrons. The Hückel’s rule states that a compound is aromatic if it is cyclic, planar, fully conjugated, and possesses (4n+2) pi electrons in the cyclic system. Aromatic compounds exhibit unique physical and chemical properties due to the delocalization of pi electrons around the ring, making them more stable and less reactive than non-aromatic compounds.
