उत्तर
Fehling’s solution
Explanation:
Acetones belong to the ketonic functional category. To distinguish between aldehyde and ketone, utilise Fehling's solution. Carbonyl groups are found in sodium hydrogen sulphite, phenyl hydrazine and Grignard reagent. Ketones and aromatic aldehydes do not react with Fehling's solution.
