Do Alkenes Have Hydrogenation?

When alkenes react with hydrogen gas in the presence of a variety of metal catalysts, a hydrogen molecule will be added to the double bond in the way that each carbon atom bonded with one hydrogen atom, such addition reaction is called hydrogenation.

Do alkenes undergo hydrogenation?

Introduction. One important alkene addition reaction is hydrogenation., where the alkene undergoes reduction to an alkane. In a hydrogenation reaction, two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane.

Does hydrogenation of alkenes require a catalyst?

Although the hydrogenation of an alkene is a thermodynamically favorable reaction, it will not proceed without the addition of a catalyst. Common catalysts used are insoluble metals such as palladium in the form Pd-C, platinum in the form PtO2, and nickel in the form Ra-Ni.
