Question

question 14 (10 points) listen the contents on a box of cupcakes lists partially hydrogenated soybean oil. partial hydrogenation of soybean oil has what effect? it produces fatty acid salts. it decreases the percent of unsaturation that is present. it hydrolyzes the triacylglycerol. it increases the number of fatty acids present. it decrease the number of hydrogen atoms present on the molecule. question 15 (10 points) saved

Explanation:

1. Analyze each option:

• Option 1: Fatty acid salts are produced by saponification (reaction with base), not hydrogenation. So this is incorrect.
• Option 2: Partial hydrogenation adds hydrogen to unsaturated fatty acids (with double bonds), converting some double bonds to single bonds. This decreases the degree of unsaturation (since unsaturation is related to double bonds). This is correct.
• Option 3: Hydrolysis of triacylglycerol breaks it into fatty acids and glycerol, which is not hydrogenation. Incorrect.
• Option 4: Hydrogenation doesn't increase the number of fatty acids; it modifies the existing fatty acid chains. Incorrect.
• Option 5: Hydrogenation adds hydrogen atoms (increases, not decreases) to the molecule. Incorrect.

Answer:

B. It decreases the percent of unsaturation that is present.
