Preparation of vegetable ghee involves:
Correct answer: B. Hydrogenation
- A. Halogenation
- B. Hydrogenation
- C. Hydroxylation
- D. Dehydrogenation
Explanation
Hydrogenation of alkenes or alkynes in the presence of nickel at 200-300*C yields alkanes. The hydrogenation can also be carried out with platinum or palladium at room temperature but they are expensive than nickel. The method is of industrial importance. Production of vegetable ghee by the catalytic hydrogenation of vegetable oil (unsaturated fatty acids) is an example of the application of this method on industrial scale.
