Vedclass · Answer

(C) Fehling's solution is a mild oxidizing agent used to distinguish between aldehydes and ketones. Aldehydes (except benzaldehyde) and $\alpha$-hydroxy ketones (like glucose) give a positive test with Fehling's solution. Ketones,such as $CH_3COCH_3$ (propanone),do not react with Fehling's solution because they cannot be easily oxidized. Therefore,propanone is the correct answer.
