Vedclass · Answer

(D) Fehling's solution is a tartaric acid complex of cupric ions.When acetaldehyde is heated with Fehling's solution,it undergoes oxidation to form an acetate ion,while the cupric ions $(Cu^{2+})$ are reduced to cuprous oxide $(Cu_2O)$.The chemical reaction is:$CH_3CHO + 2Cu^{2+} + 5OH^{-} \xrightarrow{\Delta} CH_3COO^{-} + Cu_2O \downarrow + 3H_2O$The red precipitate formed is $Cu_2O$ (cuprous oxide).

When acetaldehyde is heated with Fehling's solution,it gives a red precipitate of:
