Alkenes can be hydrogenated.
The addition of hydrogen to an unsaturated hydrocarbon to obtain a saturated hydrocarbon is called hydrogenation.
Example: Ethene reacts with hydrogen in the presence of finely divided nickel as catalyst to form ethane.
Liquid vegetable oils are hydrogenated into vegetable ghee (solid fat).
CH2 = CH2 + H2 + Ni Catalyst → CH3 - CH3
