Propan-1-ol and propan-2-ol can be best ...

Propan-1-ol and propan-2-ol can be best distinguished by :

A

Oxidation with `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 Fehing solution.

D

Oxidation with concentrated `H_(2)SO_(4)` followed by reaction with Fehling solution.

Text Solution

Verified by Experts

The correct Answer is:
C
Propan-1-ol and propan-2-ol upon heating with copper will give propanal `(CH_(3)CH_(2)CHO)` and propanone `(CH_(3)COCH_(3))` which can be distinguished by Fehling solution. Both (a) and (b) are incorrect as propan-1-ol will be oxidised to propanoic acid which cannot be distinguished from propanone by Fehling solution. Similarly (d) is also incorrect as `H_(2)SO_(4)` does not oxidise an alcohol.
