Chemistry - Thermochemistry Question with Solution | TestHub

Question Explanation:

Calculate the resonance energy of Anthracene using hydrogenation data.

Concept:

Resonance Energy and Enthalpy of Hydrogenation.

Solution:

Resonance energy is the difference between the experimental enthalpy of hydrogenation and the theoretical value calculated for a localized structure (based on isolated double bonds). Anthracene contains 7 double bonds in its structure.

Final Answer: $-84\frac{\mathrm{kcal}}{\mathrm{mol}}$
