Question:
Which of the following tests is used to identify ketones ?
Which of the following tests is used to identify ketones ?
Show Hint
Tollen's, Schiff's and Fehling's tests are for aldehydes, while the nitroprusside test is for ketones.
Updated On: Nov 12, 2026
- Sodium nitroprusside test
- Tollen's test
- Schiff test
- Felhing test
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Aldehydes are easily oxidised and give positive results with Tollen's, Fehling's and Schiff's reagents, whereas ketones do not.
Step 2: Test for ketones
Ketones having an alpha hydrogen react with sodium nitroprusside in alkaline medium to give a red or wine-red colour.
Step 3: Choose the option
The sodium nitroprusside test is therefore the one used to identify ketones.
Final Answer:
The sodium nitroprusside test identifies ketones. \[ \boxed{\text{(A) }\text{Sodium nitroprusside test}} \]
