What Is Hydrogenation? Chemistry Definition

Hydrogenation is a reduction reaction which results in an addition of hydrogen (usually as H 2).If an organic compound is hydrogenated, it becomes more "saturated" with hydrogen atoms. The process typically requires the use of a catalyst, since hydrogenation only occurs spontaneously at high temperatures.

hydrogenation of alkenes - chemguide

The relatively high temperatures used in the hydrogenation process tend to flip some of the carbon-carbon double bonds into the "trans" form. If these particular bonds aren't hydrogenated during the process, they will still be present in the final margarine in molecules of trans fats.. The consumption of trans fats has been shown to increase cholesterol levels (particularly of the more harmful .

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.
