An 8A student did the reaction below initially at 0°C. Gas chromatography of a small sample of the reaction showed that compound A was the major product. Instead of stopping the reaction the student accidentally allowed it to reach 40°C before working it up. To their surprise, GC analysis now showed B was the major product. Cooling it back to 0°C did not alter the result. Using a reaction coordinate diagram and mechanisms explain what happened? B H-Br Br Br At 0°C 71% 29% At 40°C 15% 85%
