Question

The heats of hydrogenation of cycloheptene and $1,3,5$ -cycloheptatriene are $110 \mathrm{~kJ} / \mathrm{mol}(26.3 \mathrm{kcal} / \mathrm{mol})$ and $305 \mathrm{~kJ} / \mathrm{mol}(73.0$ kcal/mol), respectively. In both cases cycloheptane is the product. What is the resonance energy of $1,3,5$ -cycloheptatriene? How does it compare with the resonance energy of benzene?

Step 1

Given: Heat of hydrogenation of cycloheptene = $110 \mathrm{~kJ/mol}$ Heat of hydrogenation of $1,3,5$-cycloheptatriene = $305 \mathrm{~kJ/mol}$ Resonance energy = Heat of hydrogenation of $1,3,5$-cycloheptatriene - Heat of hydrogenation of cycloheptene Resonance Show more…
