How do you explain the formation of furanose structure for fructose while glucose forms pyranose structure with same molecular formula C_6H_12O_6 ? |
Answer» Solution :D-glucose , an aldohexose GIVES the characteristics reactions of aldehydic group (e.g., with HCN tollen's reagent, fehling reagent etc.,) but penta acetate of D-glucose does not give these reactions. It means that either - CHO group is absent or it is not available for the chemical reactions in penta ACETYL glucose . Infact , the aldehydic group is a PART of HEMIACETAL structure which penta acetyl glucose has. So , it not available for REACTION.
