उत्तर
Propanol is converted into propanoic acid by the oxidation reaction.
The chemical equation for the above reaction is as follows:
CH3-CH2-CH2-OH → CH3CH2COOH
Propanol is oxidised to propanoic acid in the presence of alkaline potassium permanganate solution (alkaline KMnO4). Alkaline potassium permanganate solution acts as an oxidising agent as it adds oxygen to convert propanol to propanoic acid.
