What is hydrogenation ??

 

Hydrogenation is the process of addition of hydrogen to an unsaturated organic compound (compounds containing double or triple bond) to convert it into a saturated compound (compound containing only single bonds). This process requires catalyst, non-catalyzed hydrogenation occurs only at very high temperatures. For example,the addition of hydrogen to ethene (CH₂=CH₂) in the presence of nickel catalyst is hydrogenation.

The process of hydrogenation is also used in saturation of vegetable oil.
