- Hydrogenation of 1,3-cyclohexadiene and benzene are both exothermic, but benzene requires much more forcing conditions than 1,3-cyclohexadiene to get hydrogenated. when 1,3-cyclohexadiene is hydrogenated, more heat is released than with benzene, even though benzene adds three H2 molecules and 1,3-cyclohexadiene only ads two per molecule.
