Question
Explain the given reaction with the example:

Hydrogenation reaction.

✓

Answer

Addition of hydrogen to unsaturated hydrocarbon to obtain a saturated hydrocarbon is called hydrogenation reaction. Hydrogenation is used for converting unsaturated vegetable oil into fat. This can be shown by following equation:

$\text{R}_2\text{C}=\text{CR}_2+\text{H}_2\xrightarrow{\ \ \ \text{Ni}\ \ \ }\text{R}_2\text{C}-\text{CR}_2\\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\ \ \ \ \ \ |\\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{H}\ \ \ \ \ \text{H}$
