ConceptChemical Properties of Carbon Compounds - Addition Reaction

#### Question

What is hydrogenation? What is its industrial application?

#### Solution 1

Hydrogenation is the chemical reaction between hydrogen and other compounds in the presence of catalyst. Hydrogenation is used mainly to reduce saturated hydrocarbons. Hydrogenation is an addition reaction.For Example: When ethene is heated with the catalyst nickel it is reduced to ethane.

Industrial application:

→ Hydrogenation is used in many industrial applications. For example; in Petrochemical Industry, hydrogenation is used to convert alkenes into alkanes (paraffins) and cycloalkanes.
→ It is also used to prepare vegetable ghee from vegetable oils.

#### Solution 2

Hydrogenation is the process of adding hydrogen to an unsaturated hydrocarbon for obtaining a saturated hydrocarbon in the presence of a catalyst.

Chemical reaction: CR_2 = CR_2 + H_2   HCR_2 - HCR_2

Industrial application: The hydrogenation process is used to make ghee (saturated fat) from vegetable oils (unsaturated fat).
