Q78jee_main_2024_31_jan_morningReactions of Glucose
Match List I with List II
LIST-I
LIST-II
A. Glucose/NaHCO₃$NaHCO_3$/Δ$\Delta$
I. Gluconic acid
B. Glucose/HNO₃$HNO_3$
II. No reaction
C. Glucose/HI/Δ$\Delta$
III. n-hexane
D. Glucose/Bromine water
IV. Saccharic acid
Choose the correct answer from the options given below:
Matching the reactions of glucose:
(A) Glucose does not react with NaHCO₃$NaHCO_3$, so there is no reaction. (A arrow$\rightarrow$ II)
(B) Oxidation of glucose with strong oxidizing agents like HNO₃$HNO_3$ yields a dicarboxylic acid called saccharic acid. (B arrow$\rightarrow$ IV)
(C) Prolonged heating of glucose with HI$HI$ forms n-hexane, indicating a straight chain of six carbon atoms. (C arrow$\rightarrow$ III)
(D) Oxidation with mild agents like bromine water converts glucose to gluconic acid. (D arrow$\rightarrow$ I)
