Updated On: Feb 5, 2026
- 2,4-DNP reagent
- Saturated NaHSO$_3$ solution
- Fehling solution
- Lucas reagent
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Nature of products.
Acidic hydrolysis produces one aldehyde and one ketone.
Step 2: Differentiation.
Fehling solution gives a positive test with aldehydes but not with ketones.
Step 3: Conclusion.
Fehling solution can distinguish between P and Q.
Acidic hydrolysis produces one aldehyde and one ketone.
Step 2: Differentiation.
Fehling solution gives a positive test with aldehydes but not with ketones.
Step 3: Conclusion.
Fehling solution can distinguish between P and Q.
