Which of the following compounds develops a pink color with Schiff's reagent?
Show Hint
Schiff's reagent is restored to pink by aldehydes only.
Updated On: Nov 12, 2026
- Acetaldehyde
- Acetone
- Acetic acid
- Methyl acetate
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Schiff's reagent is rosaniline hydrochloride decolourised by \(\text{SO}_{2}\).
Aldehydes restore its pink colour.
Step 2: Classify the Options
Acetaldehyde is an aldehyde, acetone is a ketone, acetic acid is a carboxylic acid and methyl acetate is an ester.
Step 3: Conclusion
Only the aldehyde gives the pink colour, option (A).
Final Answer:
Acetaldehyde gives the pink colour, option (A). \[ \boxed{\text{(A) }\text{Acetaldehyde}} \]
