Q. 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
Explanation
(c)
Catalytic dehydrogenation involves the passing of vapours of alcohol over reduced copper at $300℃$ and the product thus formed is identified.
