Answer:
Explanation:
given The enthalpy of hydrogenation of cyclohexene is -1 19.5 kilo joule per mole and resonance energy of benzene is - 150.4 kilo joule per mole the enthalpy of hydrogenation would be
Given
Enthalpy of hydrogenation of cyclohexene = - 119 KJ / mol that is C = C
Therefore enthalpy of hydrogenation of benzene will be – 119 x 3 = - 357 K J / mol
Resonance energy of benzene = Δ h Exp – Δ h cal
-150.4 = - 357 - Δ h cal
Δ h cal = - 206.6 KJ / mol
Therefore enthalpy of hydrogenation of benzene will be – 206.6 K J / mol
