Catalytic Hydrogenation of Alkenes - Chemistry LibreTexts

Introduction. An example of an alkene addition reaction is a process called hydrogenation.In a hydrogenation reaction, two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane.Hydrogenation of a double bond is a thermodynamically favorable reaction because it forms a more stable (lower energy) product.
