The breaking of C-O, C-S, and C-N bonds is much easier than the breaking of C-C bonds; Desulfurization > Deoxidation > Denitration ; Cycloenes > Alkenes >> Aromatics ; Polycyclic > Bicyclic >> Monocyclic
Dehydrogenation; Diene; Sulfur; Oxygen; Monoenene; Nitrogen; Aromatic hydrocarbons
The order of hydrogenation reactions from easiest to hardest is: desulfurization > deoxygenation > denitrogenation
(1) The breaking of C—O, C—S, and C—N bonds is much easier than the breaking of C—C bonds. (2) Desulfurization > Deoxygenation > Denitration. (3) Cycloenes > Alkenes > Aromatics. (4) Polycycles > Bicyclics > Monocycles
