1-propanol and 2-propanol can be best distinguished by :

Options

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.

Answer

C

Explanation

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.
