what could be observed on adding a 5% alkaline potassium permagnate solution drop by drop to some warm ethanol in a test tube. write the name of the compound formed during the reaction and the chemical equation of the reaction taking place.

Potassium permanganate (KMnO4) is a very strong oxidant able to convert primary alcohols to carboxylic acids. Normally these oxidations are performed under strong alkaline conditions using 1N NaOH or KOH solution, because this promotes a greater oxidation speed and selectivity. 

When ethanol reacts with 5% alkaline KMnO4 solution, it gives ethanoic acid as a product. It is explained by following reaction:

  • 3

Ethanol gets oxidised resulting in the formation of ethanoic acid.

C2H5-OH ----(Alkaline KMnO4 + Heat)-----> CH3COOH + H2O

Hope this helps u........

ethanoic acid will be formed and the if u add  alka potassium permagnete to ethanol then the color will change and when the color completely changes then it is convwerted to ethanoic acid

ch3ch2oh------alkaline potassium permagnete------ ch3cooh

 

hope this helps
