what happens when ethanol is oxidised with acidified by KMnO4 solution?

CH3CH2OH     --->    CH3COOH
                       KMnO4
  • Ethanol when reacts with acidified KMnO4 undergo oxidation to form ethanoic acid
  • When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen.
  • KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process.

ACIDIFIED KMnO4 OXIDISES ALCOHOLS TO CARBOXYLIC ACIDS VIA ALDEHYDES  DIRECTLY BECAUSE OF ITS STRONG OXIDISING NATURE.
CH​3CH2 OH---​CH​3CHO-​-​CH​3COOH

HOWEVER MEDIUM OXIDISING AGENTS LIKE  ANHYDROUS CrO3 ,PCC  CAN BE EMPLOYED TO ISOLATE AT THE ALDEHYDE STAGE.
