Acetone

Vedclass · Answer

(A) The correct answer is $A$. Fehling solution is a mild oxidizing agent used to distinguish between aldehydes and ketones. Aldehydes (like acetaldehyde and formalin) and reducing sugars (like $D^{-}$-glucose) are oxidized by Fehling solution to give a brick red precipitate of $Cu_2O$. Ketones,such as acetone,are not easily oxidized by Fehling solution because they require a stronger oxidizing agent to break the $C-C$ bond. Therefore,acetone does not give a brick red precipitate.
