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

A

Glucose forms pentaacetate

B

Glucose reacts with hydroxylamine to form an oxime

C

Pentaacetate of glucose does not react with hydroxyl amine

D

Glucose is oxidised by nitric acid to gluconic acid

Text Solution

Verified by Experts

The correct Answer is:
C
“Pentaacetate of glucose does not react with hydroxylamine” showing absence of free CHO group. This can not be explained by open structure of glucose. While all other properties are easily explained by open structure of glucose.
