Vedclass · Answer

(B) Fehling solution is a mild oxidizing agent used to distinguish between aliphatic and aromatic aldehydes.Aliphatic aldehydes (like $CH_3CHO$,$CH_3CH_2CHO$,and $HCHO$) are easily oxidized by Fehling solution to their corresponding carboxylate ions,resulting in a reddish-brown precipitate of $Cu_2O$.Aromatic aldehydes (like $Ph-CHO$) are not strong enough reducing agents to reduce the $Cu^{2+}$ ions in Fehling solution.Therefore,$Ph-CHO$ does not reduce Fehling solution.
