Is Lobry Van Bruyn Transformation the same as the Tautomerization of Fructose during Fehling’s test? Would Fehling’s reagent react with ketoses or is it strictly for aldoses? If yes, why do they need to tautomerize first? What would be the reaction and product when Fehling’s reagent reacts with non-reducing sugars?
