Vedclass · Answer

(A) Glucose contains $5$ hydroxyl $(-OH)$ groups ($4$ secondary and $1$ primary).When glucose reacts with excess acetic anhydride,all $5$ hydroxyl groups are acetylated to form glucose pentaacetate.The reaction is as follows:$CHO(CHOH)_4CH_2OH + 5(CH_3CO)_2O \xrightarrow{Pyridine} CHO(CHOCOCH_3)_4CH_2OCOCH_3 + 5CH_3COOH$As shown in the reaction,$5$ moles of acetic acid $(CH_3COOH)$ are produced for every mole of glucose reacted.

How many moles of acetic acid are obtained in the reaction when one mole of glucose is treated with excess acetic anhydride (in $moles$)?
