Match the reactions of Glucose given in Column I with the major product formed in the reaction as in Column II. Column I - Reactions Column II - Major Product A C₆H₁₂O₆ + HI (Heat) P HOOC-(CHOH)₄-COOH B C₆H₁₂O₆ + Br₂ (aq) Q CH₃-(CH₂)₄-CH₃ C C₆H₁₂O₆ + Conc. HNO₃ R NH₄OOC-(CHOH)₄-CH₂OH D C₆H₁₂O₆ + 2[Ag(NH₃)₂]OH S HOOC-(CHOH)₄-CH₂OH

Step-by-step solution

A + HI (Heat): Strong reduction, removes all OH groups n-hexane CH₃-(CH₂)₄-CH₃ A = Q B + Br₂ (aq): Mild oxidation, only oxidises aldehyde ( -CHO ) at C₁ Gluconic acid HOOC-(CHOH)₄-CH₂OH B = S C + Conc. HNO₃ : Strong oxidation, oxidises both aldehyde and terminal -CH₂OH Saccharic acid HOOC-(CHOH)₄-COOH C = P D + 2[Ag(NH₃)₂]OH : Tollens reagent, mild oxidation in basic medium Ammonium gluconate NH₄OOC-(CHOH)₄-CH₂OH D = R A = Q, B = S, C = P, D = R
