Question
Match List - I with List - II. array l List - I & List - II \\ Reaction of Glucose with & Product formed \\ A. Hydroxylamine & I. Gluconic acid \\ B. Br _ 2 water & II. Glucose pentacetate \\ C. Excess acetic anhydride & III. Saccharic acid \\ D. Concentrated HNO _ 3 & IV. Glucoxime array Choose the correct answer from the options given below :
Options
- A. A-III, B-I, C-IV, D-II
- B. A-I, B-III, C-IV, D-II
- C. A-IV, B-III, C-II, D-I
- D. A-IV, B-I, C-II, D-III
Answer
D. A-IV, B-I, C-II, D-III
Step-by-step solution
Glucose reactions: A + Hydroxylamine forms glucoxime (IV) via condensation with aldehyde group. B + Br₂ water oxidizes aldehyde to carboxylic acid, forming gluconic acid (I). C + Excess acetic anhydride acetylates all hydroxyl groups to form glucose pentaacetate (II). D + Concentrated HNO₃ oxidizes both aldehyde and primary alcohol groups to form saccharic acid (III). The correct matching is A-IV, B-I, C-II, D-III.
