The following reactive intermediate molecule has three additional resonance structures. Depict these resonance structures using the curved-arrow formalism to push electrons. Circle the major structure.

For the following acid/base reaction, please identify the acid (A), base (B), conjugate acid (CA), and conjugate base (CB) in the provided boxes.

In the reaction below: (a) Draw the structures corresponding to the appropriate conjugate acid and conjugate base. Please place your answers in the boxes provided below. (b) Use the curved-arrow formalism to provide an arrow-pushing mechanism to depict the movement of electrons. (c) Draw the equilibrium arrows for this reaction in the dotted box below to show which side the equilibrium will lie. (d) Using 1-2 sentences, briefly rationalize why the equilibrium in the above reaction favors the direction you drew. Pictures/structures may be used to help support your answer.
