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 hydroxylamine

D

glucose is oxidised by nitric acid to gluconic acid

Text Solution

Verified by Experts

The correct Answer is:
C
Glucose pentaacetate does not contain a free `-OH` group at `C-1`, because it is converted to `-OAc` group. So the ring does not open up for conversion to open chain aldehydic form
