Question

Reaction of glucose with acetic anhydride indicates the presence of (A) five OH groups (B) CHO group (C) three OH groups (D) none of these

Tardigrade Admin · Accepted Answer

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.
