Name the functional group of organic compounds that can be hydrogented.
(CBSE 2013, 2012)

Ethene (CH2=CH2) can be hydrogenated.

The addition of hydrogen to an unsaturated hydrocarbon in the presence of catalysts such as palladium or nickel to give a saturated hydrocarbon is called hydrogenation.

Example: Ethene (CH2=CH2) reacts with hydrogen in the presence of nickel catalyst to produce ethane (CH3-CH3).

This reaction is commonly used in hydrogenation of vegetable oil into vegetable ghee (solid fat)
