Question: 69
9. Successfully converting 3-phenylpropanol to 3-phenylpropanoic acid by the Jones oxidation requires CrO3, acetone, and:
- A. dilute sulfuric acid.
- B. dilute sodium hydroxide.
- C. anhydrous conditions.
- D. high temperature.
Correct Answer: A
Explanation:
Acidic conditions, provided by dilute sulfuric acid, are required to complete the Jones oxidation. This reaction is carried out in aqueous conditions, eliminating choice (C). While heat may speed up the reaction, high temperatures are not required for this reaction, eliminating choice (D).
