Which of the following reactions cannot explain why D-Glucose was assigned the following structure?

Options

  1. AThe pentaacetate of glucose does not react with hydroxylamine indicating the absence of a free CHO group.
  2. BAcetylation of glucose with acetic anhydride gives glucose pentaacetate which confirms the presence of five –O
  3. COn prolonged heating with HI, it forms n-hexane
  4. DOn oxidation with nitric acid, glucose as well as gluconic acid both yield a dicarboxylic acid, saccharic acid

Correct answer

A. The pentaacetate of glucose does not react with hydroxylamine indicating the absence of a free CHO group.

Step-by-step solution

Correct Option is : (A) The pentaacetate of glucose does not react with hydroxylamine indicating the absence of a free CHO group.
