Concept explainers
(a)
Interpretation:
To propose a mechanism for the reaction of acetic anhydride with water.
Concept introduction:
The reaction of acetic anhydride with water is a nucleophilic substitution reaction. The nucleophile from the reagent attacks the carbonyl carbon in acetic anhydride to form a tetrahedral intermediate. The carboxylate ion leaves the intermediate leading to form the corresponding product.
(b)
Interpretation:
The difference in the mechanism for the reaction of acetic anhydride with water and acetic anhydride with alcohol has to be explained.
Concept introduction:
The reaction of acetic anhydride with water is a nucleophilic substitution reaction. The nucleophile from the reagent attacks the carbonyl carbon in acetic anhydride to form a tetrahedral intermediate. The carboxylate ion leaves the intermediate leading to form the corresponding product.
