Question:
Identify the use of Baeyer's reagent by the following.
Identify the use of Baeyer's reagent by the following.
Show Hint
Baeyer reagent is cold dilute alkaline KMnO4, used in the test for unsaturation.
Updated On: Oct 1, 2026
- Detecting the presence of carbon carbon double bond.
- Polymerisation
- Oxidation
- Reduction
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: What it is
Baeyer's reagent is a cold, dilute, alkaline solution of \(KMnO_4\).
Step 2: Use
It is decolourised (pink to brown ppt) by compounds with a carbon-carbon double or triple bond. This is the test for unsaturation.
Polymerisation, general oxidation and reduction are not the specific use asked here.
Final Answer:
It detects a carbon-carbon double bond. \[ \boxed{\text{(A)}\ \text{Detecting C=C bond}} \]
