The alcohols, propan-1ol and propan-2-ol are distinguished by

Options

A. oxidation with conc. `H_(2)SO_(4)` followed by reaction with Fehling solution
B. oxidation with alkaline `KMnO_(4)` followed by reaction with Fehling solution
C. reaction with iodine and aqueous `NaOH`
D. reaction with Lucas reagent

Answer

D

Explanation

The compounds cotaining `CH_(3)-underset(OH)underset("| ")"CH"-` group are distinguished from other alcohols through iodoform test (reaction of alcohol with `I_(2)` and aq. NaOH.)
`underset("Propanol")(CH_(3)-CH_(2)-CH_(2)OH)+I_(2)+NaOH overset(Delta)rarr "No reaction"`
`underset("2-Propanol")(CH_(3)-underset(OH)underset("| ")"CH"-CH_(3))+4I_(2)+6NaOH overset(Delta)rarr "No reaction" `
