Vedclass · Answer

(D) non-reducing sugar is a carbohydrate that does not contain a free aldehyde or ketone group,meaning it cannot reduce Tollens' reagent or Fehling's solution.Sucrose is a disaccharide where the glycosidic linkage is between the anomeric carbons of glucose and fructose,leaving no free hemiacetal or hemiketal group.Starch and cellulose are polysaccharides where the anomeric carbons are involved in glycosidic linkages,making them non-reducing as well.Therefore,all the given options are non-reducing sugars.

List-$I$	List-$II$
$A$. Glucose/$NaHCO_3$/$\Delta$	$I$. Gluconic acid
$B$. Glucose/$HNO_3$	$II$. No reaction
$C$. Glucose/$HI$/$\Delta$	$III$. $n$-hexane
$D$. Glucose/Bromine water	$IV$. Saccharic acid
