Question

Why should we prefer vegetable oils over animal fats for cooking food give a balanced chemical equation for the reaction for hydrogenation of vegetable oils name the catalyst in this reaction

Answer 1

As we know Vegetable oil contains unsaturated fatty acids, and is liquid at room temperature. When they are hydrogenated, they become saturated and change to a solid state i.e ghee. Vegetable oil contains unsaturated fatty acids that are essential for our well-being, whereas saturated fatty acids like those present in ghee are not healthy. Therefore, vegetable oil should be preferred over animal fat as ghee (which is not good for health ) for cooking purposes....the balanced equation for hydrogenation of vegetable oil is given below --

CH2=CH2 + H2 (+ Ni catalyst) => CH3-CH3 This basically represents a unsaturated molecule (like vegetable oil) being hydrogenated to a saturated molecule (containing no double bonds).

Answer 2

Answer:

Explanation:Vegetable oils are unsaturated and do not lead to formation of cholesterol Animals fats are saturated lead to formation of cholesterol which can be deposited in arteries

CR2=CR2 + H2-----------》CR3--CR3
