Solution: Using arrows to show the flow of electrons, write a stepwise mechanism for the reaction shown below. Give all important resonance structures for each reactive intermediate. For your mechanism, concisely explain why X = 81% and Y = 19% when the reaction is performed at -80°C and why X = 44% and Y = 56% when the reaction is performed at room temperature (25°C).
