The enthalpy of hydrogenation of cyclohexane is – 119.5 kJ mol&n...
Cyclohexene after hydrogenation would be converted to purely saturated cyclohexane.
As cyclohexene has one pi bond its enthalpy of hydrogenation is -119.5 kJ mol-1.
In benzene there are 3 pi bonds hence the enthalpy of hydrogenation = -150.4 kJ –  3 * -119.5 kJ.
– 208.1 kg mol–1
