The reagents with which glucose does not react to give the corresponding test/products are: A. Tollen's reagent B. Schiff's reagent C. D. E.
Choose the correct option:
A and D
B and E
E and D
B and C
Despite having an aldehyde group, glucose does not give the 2,4-DNP test, Schiff's test, and it does not form the hydrogensulphite addition product with . This anomalous behaviour is because glucose exists primarily in its cyclic hemiacetal form, rendering the free aldehyde group unavailable for these specific reactions. However, it does react with Tollen's reagent, , and . Therefore, the reagents it does not react with are Schiff's reagent (B) and (E).
