Vedclass · Answer

(B) Glucose is a reducing sugar because it contains a free aldehyde group. When glucose is heated with Fehling's solution,the aldehyde group is oxidized to a carboxylate group,and $Cu^{2+}$ ions are reduced to $Cu^+$ ions. The reaction produces a red precipitate of cuprous oxide $(Cu_2O)$. Reaction: $	ext{Glucose} + 	ext{Fehling's solution} 	o 	ext{Gluconic acid} + Cu_2O 	ext{ (Red precipitate)}$.
