What is the value of '' in Huckel's electron rule for the aromatic compound Anthracene? — Hydrocarbons Chemistry Question

💡 Solution & Explanation

Anthracene is a polycyclic aromatic hydrocarbon consisting of three fused benzene rings. Its structure contains 7 double bonds, which equates to 14 delocalized $\pi$ electrons. According to Huckel's rule for aromaticity, $4n + 2 = 14 \implies 4n = 12 \implies n = 3$.
