Vedclass · Answer

(D) The reagent described is Fehling's solution,which consists of $CuSO_4$ (Fehling's $A$) and sodium potassium tartrate (Rochelle salt) in $NaOH$ (Fehling's $B$).Fehling's solution is a mild oxidizing agent used to distinguish aliphatic aldehydes from aromatic aldehydes.Aliphatic aldehydes like $CH_3CHO$,$C_2H_5CHO$,and $C_6H_5CH_2CHO$ (phenylacetaldehyde) are oxidized by Fehling's solution to their corresponding carboxylate ions.However,aromatic aldehydes like $C_6H_5CHO$ (benzaldehyde) do not react with Fehling's solution because the aldehyde group is directly attached to the benzene ring,making it resistant to oxidation by this mild reagent.Therefore,the correct option is $D$.

The alkaline $CuSO_4$ solution containing sodium potassium tartrate does not react with:
