How is resonance in naphthalene similar to that of benzene?
Naphthalene's resonance involves the delocalization of electrons over a fused ring system, leading to a more extended π system compared to benzene.
While resonance and aromaticity are shared by benzene and naphthalene, the resonance structures of the two compounds differ due to structural differences, particularly the presence of two fused rings in naphthalene. Notwithstanding these variations, both compounds' basic aromatic nature accounts for part of their stability and distinctive reactivity patterns.
