Question

Which of the following happens in hydrogenation? Question 9 options: A) Hydrogen atoms are added to fats to make them more saturated. B) Cholesterol is extracted from a product. C) Fats are made less saturated by removing hydrogen atoms. D) A saturated fat becomes a polyunsaturated fat. E) A solid fat becomes a liquid fat.

Answer 1

Answer : The correct option is, (A) Hydrogen atoms are added to fats to make them more saturated.

Explanation :

Hydrogenation : Hydrogenation means to treat with hydrogen that means it is a chemical reaction between the molecular hydrogen and the another compound or an element in the presence of catalyst like, nickel, palladium etc.

When an organic compound is hydrogenated then it becomes more saturated with the hydrogen atoms.

The largest scale application of hydrogenation is the processing of vegetable oils. Typically, vegetable oils are derived from polyunsaturated fatty acids. Their partial hydrogenation reduces most but not all of these carbon-carbon double bonds.

Liquid fats : They have the highest degree of unsaturation. Vegetable and marine oils are liquid fats.

Solid fats : They are highly saturated. Vegetable and animal fats are solid fats.

Hence, the correct option is, (A) Hydrogen atoms are added to fats to make them more saturated.
