What will you observe on adding a $5\%$ alkaline potassium permanganate solution drop by drop to some warm ethanol taken in a test tube? Write the name of the compound formed during the above chemical reaction.

(N/A) When $5\%$ alkaline $KMnO_4$ solution is added drop by drop to warm ethanol,the initial pink colour of the potassium permanganate solution disappears. This happens because the alkaline $KMnO_4$ acts as an oxidising agent and oxidises ethanol to ethanoic acid. The chemical reaction is: $CH_3CH_2OH + [O] \xrightarrow{\text{alkaline } KMnO_4} CH_3COOH + H_2O$. The name of the compound formed is Ethanoic acid.
