Which of the following is not a correct statement with regard to stearic acid and oleic acid molecules?
Correct answer: B. Both are saturated fatty acids
- A. Both are fatty acids having the same number of carbon atoms
- B. Both are saturated fatty acids
- C. One olefinic bond is present in oleic acid
- D. The alkyl group of stearic acid contains 35 hydrogen atoms
Explanation
Stearic acid is a saturated fatty acid (with no C=C double bonds). Oleic acid is a monounsaturated fatty acid, meaning it contains one C=C double bond. Therefore, the statement that both are saturated is incorrect.
