Write such reactions and facts about glucose which cannot be explained by its open chain structure

Answer 2

$\mathfrak{The\:Answer\:is}$

Open chain structure of D-glucose could not explain the following reactions:
(i) Despite having the aldehyde group, glucose does not give
Schiffs test and 2,4-DNP test.
(ii) Glucose does not react with sodium hydrogen sulphide to
form addition product.
(iii) The pentaacetate of glucose does not react with hydroxyl amine showing the absence of free —CHO group.
