The standard molar enthalpies of hydrogenation of benzene (l) at 25 o – InterviewSolution

1.	The standard molar enthalpies of hydrogenation of benzene (l) at 25 oC is −208 kJ mol−1. The standard enthalpy of hydrogenation of cyclohexene(l) at 25 oC is −119 kJ mol−1. Use these data to estimate the magnitude of the resonance energy of benzene. (correct answer +1, wrong answer -0.25)
Answer» The standard molar enthalpies of hydrogenation of benzene ( $l$ ) at $25^{o} C$ is $- 208 {kJ mol}^{- 1}$ . The standard enthalpy of hydrogenation of cyclohexene $(l)$ at $25^{o} C$ is $- 119 {kJ mol}^{- 1}$ . Use these data to estimate the magnitude of the resonance energy of benzene. (correct answer +1, wrong answer -0.25)
