The enthalpy of hydrogenation of cyclohexene is -119.5 
. If resonance energy of benzene is 
, calculate its enthalpy of hydrogenation in kJ.
Text Solution
Verified by ExpertsThe correct answer is:
-208.1
(-208.1)
The resonance energy provides extra stability to the benzene molecule so it has to be overcome, for hydrogenation to take place. So
