Question: 20 which of the statements below are false fructose gives...

Question details

20. Which of the statements below are FALSE? Fructose gives a positive test with Fehlings solution, because A- it becomes an aldose under test conditions B- fructose is converted to glucose and mannose under alkaline conditions. C- ketoses can become reducing sugars because they can isomerise (a tautomerisation) via an enediol intermediate to aldoses D) the treatment of fructose with the alkali in Fehling solution causes even decomposition of the carbon chain and more products with reducing capability are formed. E- fructose though a ketone, is a reducing sugar because in the open-chain form, a rearrangement beiween the hydroxyl group on carbon 1 and the ketone group provides an aldehyde group thal can be oxidized. F none of the above
