Acetone gives positive test with:

• A. Fehling's solution
• B. Schiff's solution
• C. 2,4 - DNP
• D. all of the above

Acetone is a type of ketone that reacts positively with certain chemical tests. Let's look at the options provided:

Test Reactions

• Fehling's Solution: This test is used for aldehydes, and acetone does not give a positive result here.
• Schiff's Solution: This test is also specific for aldehydes, so acetone will not react positively.
• 2,4-DNP (2,4-Dinitrophenylhydrazine): Acetone reacts positively with this reagent, indicating the presence of a carbonyl group.

Final Answer

Based on the reactions, the correct choice is C. 2,4 - DNP. Acetone does not give positive tests with Fehling's or Schiff's solutions.
