Question

3. The reactions below refer to questions 5-7 and illustrate the reaction steps in the anti-Markovnikov addition of HBr to (E)-prop-1-en-1-ylbenzene. Draw curved arrows that account for electron movement in reactions below and classify each reaction according to 6 patterns of radical reactions. reaction pattern Br + Br T + H-Br: - T + :Br. 4. In step a), bromine radical preferentially attaches to carbon C-2 (bromination of C-1 and formation of radical at C-2 is disfavored). Explain this observation. Explicitly mention the effect that is responsible for preferential formation of radical A over radical B. Use a drawing to support your answer.
