What is Naphthalene? - Formula, Structure & Properties 3:43 ... Witryna1 Answer. Pyrylium is aromatic. Following Hückel's rule, pyrylium is uninterrupted (no s p 3 hybridization), all atoms have p-orbitals and there is 6 π electrons. the 6 π electrons indicate that Hückel's rule ( 4 n + 2) is agreeable for pyrylium, n = 1. Hückel's rules only apply to monocycles.
