Question:
1-Propanol and 2-propanol can be distinguished by
1-Propanol and 2-propanol can be distinguished by
Show Hint
Fehling’s solution is used to test for the presence of aldehydes, which are formed when alcohols like 1-propanol are oxidized.
Updated On: Jan 12, 2026
- oxidation with alkaline KMnO\(_4\) followed by reaction with Fehling solution
- oxidation with acidic dichromate followed by reaction with Fehling solution
- oxidation by heating with copper followed by reaction with Fehling solution
- oxidation with concentrated H\(_2\)SO\(_4\) followed by reaction with Fehling solution
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand the chemical reactions.
1-Propanol and 2-propanol can be differentiated based on their oxidation products. Oxidation with acidic dichromate leads to aldehyde formation, and Fehling solution reacts with aldehydes.
Step 2: Conclusion.
Thus, the correct distinguishing method is oxidation with acidic dichromate followed by reaction with Fehling solution.
Final Answer: \[ \boxed{\text{oxidation with acidic dichromate followed by reaction with Fehling solution}} \]
