MHT CET 2023 Chemistry question

Which of the following phenomena is not explained by the open chain structure of glucose?

(A)Formation of pentaacetate of glucose with acetic anhydride
(B)Formation of oxime with hydroxylamine
(C)Formation of silver mirror with Tollen's reagent
(D)Existence of and forms of glucoseCorrect

Answer: (D)

Solution

The open chain structure of glucose (a pentahydroxy hexanal) explains: formation of a pentaacetate with acetic anhydride (five -OH groups), formation of an oxime with hydroxylamine (the -CHO group), and the silver mirror with Tollens' reagent (aldehyde group oxidised to gluconic acid). However, it cannot explain the
