Penta-acetate

Vedclass · Answer

(C) Glucose contains five hydroxyl $(-OH)$ groups. When it reacts with acetic anhydride,all five $-OH$ groups are acetylated to form glucose penta-acetate. The reaction is as follows: $CHO-(CHOH)_4-CH_2OH + 5(CH_3CO)_2O \rightarrow CHO-(CHOCOCH_3)_4-CH_2OCOCH_3 + 5CH_3COOH$ This confirms the presence of five hydroxyl groups in glucose.
