In the exhaustive catalytic hydrogenation of a single molecule of benzene to produce cyclohexane und — Aromatic Hydrocarbons Chemistry Question

💡 Solution & Explanation

To convert the highly unsaturated benzene ring ($C_6H_6$) into the fully saturated cycloalkane cyclohexane ($C_6H_{12}$), three equivalents of $H_2$ are required to saturate the equivalent of three alternating $\pi$ -bonds. The overall stoichiometry is $C_6H_6 + 3H_2 \rightarrow C_6H_{12}$.
