WebThe non-reducing sugar is not able to give a positive test for Fehling's test. During Fehling's test when free aldehyde is present it is oxidized by bistartratocuprate (II) complex to a carboxylate anion and reduces the copper (II) ions of the complex to copper (I) ions. Red copper (I) oxide then precipitates and gives the positive test.
