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.

List-$I$ $(\text{Saccharides})$	List-$II$ $(\text{Glycosidic linkages found})$
$(A)$ Sucrose	$(I)$ $\alpha 1-4$
$(B)$ Maltose	$(II)$ $\alpha 1-4$ and $\alpha 1-6$
$(C)$ Lactose	$(III)$ $\alpha 1-\beta 2$
$(D)$ Amylopectin	$(IV)$ $\beta 1-4$

Which of the following reactions of glucose can be explained only by its cyclic structure?
