Biomolecules Part 2

Concept:Glucose undergoes different reactions with various reagents to yield specific oxidation or derivatization products.Explanation:Reaction A: Glucose with hydroxylamine forms an oxime, called glucoxime. Hence A → IV.Reaction B: $Br_2$ water is a mild oxidizing agent that oxidizes the aldehyde group of glucose to carboxylic acid, producing gluconic acid. Hence B → I.Reaction C: Excess acetic anhydride acetylates all five hydroxyl groups of glucose, forming glucose pentaacetate. Hence C → II.Reaction D: Concentrated $HNO_3$ is a strong oxidizing agent that oxidizes both ends of glucose to carboxylic acid groups, yielding saccharic acid. Hence D → III.Answer:The correct match is A-IV, B-I, C-II, D-III, which corresponds to option D.
