Question

Write any two reactions of glucose which cannot be explained by the open chain structure of glucose molecule.

✓

Answer

Despite having the aldehyde group, glucose does not give $2,4-DNP$ test or Schiff’s test.
It does not form the hydrogensulphite addition product with $NaHSO_3.$
The pentaacetate of glucose does not react with hydroxylamine indicating the absence of free $–CHO$ group.
