`n-`propyl alcohol can be chemical distinguished by which reagent

A

`PCl_(5)`

B

reduction

C

oxidation with potassium dichromate

D

ozonolysis

Text Solution

Verified by Experts

The correct Answer is:
C
`n-`Propyl alcohol (`1^(@)` alcohol) and isopropyl alcohol `(2^(@)` alcohol) are oxidized by `K_(2)Cr_(2)O_(7)//H_(2)SO_(4)`. As a result, the clear orange solution turns blue-green and becomes opaque. While for isopropyl alcohol the color change is fast. Morover, the two alcohols give differents products on oxidation with `K_(2)Cr_(2)O_(7)`:
`CH_(3)CH_(2)CH_(2)OHoverset([O])rarrCH_(3)CH_(2)CHO`
`CH_(3)CH(OH)CH_(3)overset([O])rarrCH_(3)COCH_(3)`
