Homework Answers
Answer:An oil may be hydrogenated to increase resistance to rancidity (oxidation) or to change its physical characteristics. As the degree of saturation increases(Decrease in double bonds) the oil's viscosity and melting point increase.Hydrogenation also reduce the kinks in fatty acids(Kinks are due to presence of double bonds).
So correct statements are: Creates a more viscous oil and reduces branching in the fatty acid molecule.
