Question

Acetylation of glucose yields ____________.

Options

• N-Methylbenzamide

• p-toluenesulphonyl chloride

• oxime

• glucose pentaacetate

Answer 1

Acetylation of glucose yields glucose pentaacetate.

Explanation:

Acetylation of glucose with acetic anhydride gives glucose pentaacetate which confirms the presence of five –OH groups. Since it exists as a stable compound, five –OH groups should be attached to different carbon atoms.
