QUESTION 4 Which of the following is the main structural difference between molecules of fats & oils vs. laboratory ''margarine''. a. Each carbon atom in fats and oils has a total of 3 bonds, whereas each carbon atom in margarine has a total of 4 bonds. b. Each carbon atom in fats and oils has a total of 4 bonds, whereas each carbon atom in margarine has a total of 3 bonds. c. Fats and oils have more carbon-carbon single bonds than does laboratory ''margarine''. d. Fats and oils tend to have more carbon-carbon double bonds than does laboratory ''margarine''. QUESTION 5 Which one of the following catalysts is used in the 231L lab for the hydrogenation of olive oil and various vegetable oils to make ''margarine''? a. Palladium on carbon (Pd/C) b. Sodium Hydroxide (Iye, NaOH) c. Copper (Cu) d. Sulfuric Acid (H2SO4)

Explanation / Answer

4) option D is correct answer because

partial hydrogenation of a typical plant oil to a typical component of margarine. Most of the C=C double bonds are removed in this process that means fats and oil have more carbpn carbon double bond than does laboratory margarine

5) option A

generally palladium and carbon hydrogination of oliveoils and various vegetable will givemargarine.
