Answer 2

Hydrogenation is the process of changing double bond to single bond.

Explanation:

Saturated hydrocarbons are formed by the addition of hydrogen in the presence of catalysts such as palladium or nickel in unsaturated hydrocarbons, known as hydrogenation.

Industrial applications - The hydrogenation of unsaturated fats (vegetable oils) makes vegetable ghee (saturated fats).

With the help of catalyst, it gets easier to change the bond from one state of count to another.

Unsaturated are the fats, hydrogenation is used often, mostly in factories. Nickel helps as a catalyst to regain the process if it's a unsaturated fat.
