Glucose pentaacetate does not react with hydroxylamine.

Vedclass · Answer

(C) The open-chain structure of glucose fails to explain why glucose pentaacetate does not react with hydroxylamine $(NH_2OH)$.This is because the cyclic structure of glucose involves the formation of a hemiacetal,which prevents the presence of a free aldehyde group in the pentaacetate form.Therefore,the inability of glucose pentaacetate to react with hydroxylamine is evidence for the cyclic structure of glucose.
