Question

1-Propanol and 2-propanol can be distinguished by

• A. oxidation with alkaline KMnO\(_4\) followed by reaction with Fehling solution
• B. oxidation with acidic dichromate followed by reaction with Fehling solution
• C. oxidation by heating with copper followed by reaction with Fehling solution
• D. oxidation with concentrated H\(_2\)SO\(_4\) followed by reaction with Fehling solution

Hint:

Fehling’s solution is used to test for the presence of aldehydes, which are formed when alcohols like 1-propanol are oxidized.

Answer 1

The Correct Option is B

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: \[ \boxed{\text{oxidation with acidic dichromate followed by reaction with Fehling solution}} \]
