The polycyclic aromatic hydrocarbon Anthracene () consists of three fused benzene rings. According t — Hydrocarbons Chemistry Question

💡 Solution & Explanation

Anthracene contains three linearly fused benzenoid rings. The molecule features 7 distinct conjugated double bonds across its planar skeletal framework. Each double bond contributes 2 $\pi$ electrons to the delocalized cyclic cloud, resulting in a total of 14 $\pi$ electrons. Applying Huckel's rule: $4n + 2 = 14 \implies 4n = 12 \implies n = 3$.
