1. (4 pts) A chemist ran the two reactions shown below under two different conditions. Br₂ Product X -20°C Br₂ Product Y 60°C la. (1 pt) Propose reasonable structures for both Product X and Product Y 1b. (1 pt) Draw a mechanism which accounts for both X and Y. 1c. (1 pt) Why do you think X predominates at -20°C and Y predominates at 60°C? 1d. (1 pt) If the chemist took a pure solution of X and raised its temperature to 60C what do you suppose would happen, at least in part? If anything does happen, propose a mechanism to support your prediction.
