The hydrocarbon naphthalene is a white solid with characteristic odor and molecular formula C₁₀H₈ (${\mathit{M}}_{\mathit{r}}$ 128,173 $\text{g}{\text{mol}}^{-1}$). It is a bicyclic aromatic compound, i.e. two benzene rings are fused (annulated) sharing two carbon atoms. The aromatic π-electron system extends over all ten carbon atoms.
