Enumerate the reactions of D-glucose which cannot be explained by its open chain structure.

Explanation

(1) D-glucose does not form `NaHSO_(3)` additional product, aldehyde ammonia adduct, 2, 4-DNP derivative and does not respond to Schiff's reagent test.
(2) When dissolved in aqueous solution, both `alpha`-D-glucose exhibit the phenomenon of mutarotation.
(3) Glucose reacts with `NH_(2)OH` to form an oxime but pentaacetyl derivative of glucose does not react with `NH_(2)OH`.
(4) D-glucose reacts with methanol in presence of dry HCl gas to form two isomeric methyl-D-glucosides.
