Quizplus · Accepted Answer

The given reaction is the conversion of an aldehyde to an acid using KMnO4 in basic medium. The KMnO4 oxidizes the aldehyde to the corresponding carboxylate ion, which then reacts with the acidification of the solution to release the carboxylic acid. Thus, the product is III, which is the carboxylic acid. None of the other options correspond to the expected products of this reaction.
