1- Sucrose does not react with Fehling's reagent because A- Sucrose is not a reducing sugar. B) The anomeric carbon of glucose is involved in the glucose- fructose bond and hence is not free to form the aldehyde in solution. C) The monosaacharide constituents of sucrose no longer have an anomeric carbon with a free potential aldehyde or ketone group, and therefore no longer exhibits reducing properties. D) sucrose is a disaccharide of glucose and fructose in which the oxygen...
