Question

Draw the mechanism for the proton transfer step. Explain why the products of this step are favored over the reactants. 

The image illustrates a chemical reaction involving proton transfer. - **Reactant**: The structure on the left is a compound with an amide group (NH₂) attached to an acetyl group (CH₃-C=O) and connected to a phenolic group (OH) on a benzene ring. - **Reagents**: The reaction involves hydroxide ion (-OH) acting as a base. - **Mechanism**: The hydroxide ion abstracts a proton (H⁺) from the hydroxyl group of the phenol, leading to a proton transfer. - **Product**: The resulting structure on the right side is the deprotonated form (phenoxide ion) of the phenol, with the amide group remaining unchanged. Water (H₂O) is depicted as a byproduct of the reaction. This image can help students understand the concept of acid-base reactions, specifically proton transfer in organic chemistry.
