Name the reaction which is commonly used in the conversion of vegetable oils to fats. Explain the reaction involved in detail.

Hydrogenation is used to reduce vegetable oils to vanaspati ghee. Vanaspati ghee is used as a substitute for butter containing animal fats which are harmful to our health and is cheaper than butter. Vegetable oils are unsaturated and they are hydrogenated in the presence of catalysts like nickel or palladium. Hydrogenation is the process of addition of hydrogen to unsaturated compounds to form saturated compounds. The chemical reaction can be represented by the equation:
