Question:
Collin's reagent is used to convert ________.
Collin's reagent is used to convert ________.
Show Hint
Collin's reagent is used to convert ____.
Updated On: Apr 15, 2026
- $-CH_{2}OH \rightarrow -CHO$
- $-CHO \rightarrow -COOH$
- $-CHO \rightarrow -CH_{2}OH$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Composition
Collin's reagent is a complex of chromium trioxide with pyridine ($CrO_{3} \cdot 2C_{5}H_{5}N$) in dichloromethane.
Step 2: Action
It is a mild oxidizing agent.
Step 3: Conversion
It specifically oxidizes primary alcohols ($-CH_{2}OH$) to aldehydes ($-CHO$) without further oxidation to carboxylic acids.
Final Answer: (B)
