n -Propyl alcohol and isopropyl alcohol can be chemically distinguished by which reagent?
Options
- APCl ₅
- BReduction
- COxidation with potassium dichromate
- DOzonolysis
Correct answer
C. Oxidation with potassium dichromate
Step-by-step solution
Isopropyl alcohol and n-propyl alcohol can be chemically distinguished by oxidation with potassium dichromate.n-propyl alcohol on oxidation with potassium dichromate gives an aldehyde. Isopropyl alcohol on oxidation with potassium dichromate gives a ketone. During oxidation of potassium dichromate, solution of potassium dichromate turns bluegreen in the reactions. For isopropyl alcohol this colour change is fast and for n -propyl alcohol the colour change is slow. Isopropyl alcohol and n-propyl alcohol are examples
