PPT-Pd /C and Hydrogenation

Pd C Hydrogenations Danger comes from the active catalysts Absorb hydrogen gas Can spark spontaneously and may ignite on exposure to air Readily causes ignition of flammable solvents in the presence of air. 6 286 Relative Stability of Alkenes Based On Molar Heats of Hydrogenation H hyd 276 kcalmol H hyd 286 kcalmol Trans cis brPage 3br Relative Stability of Alkenes Based On Molar Heats of Hydrogenation 327 kcalmol 297 kcalmol 280 kcalmol 286 kcalmol The relative stabilities of related alkenes can be determined by measuring their heats of combustion.. The thermodynamic stability of the butenes increases in the order: 1-butene < cis-2-butene < trans-2-butene.. Chem. Rev. 129 ROBERT A. H.
