a. Provide a detailed, stepwise mechanism for the transformation above that accounts for the
formation of product II. Use the curved arrow formalism to show the flow of electrons. Show
all lone pairs, intermediates, formal charges, and pertinent resonance structures.
b. Explain why product II is formed instead of product III. Use drawings to support your answer.
