Which of the following reagents could be used to distinguish between propan-1-ol and propan-2-ol

A.

H+ / K2Cr2O7

B.

I\(_2\) / OH-

C.

CH\(_3\)COOH

D.

NaCl

Correct answer is A

when a primary alcohol like ethanol is warmed with excess of an oxidizing reagent, such as acidified Potassium permanganate( KMnO₄) or acidified Potassium dichromate(VI) ( K2Cr2O7 ), it is oxidized first to ethanal then to ethanoic acid, WHILE

Secondary alcohols like butan-2-ol will be oxidized to alkanones

propan-1-ol - primary alcohol,

propan-2-ol- secondary alcohol

- The Lucas test in alcohols is a test to differentiate between primary, secondary, and tertiary alcohols. It is based on the difference in reactivity of the three classes of alcohols with hydrogen halides
