22. Answer ALL parts of this question. (a) Cyclohexene will react with Br2 in an inert solvent (such as chloroform) or in water. The product in each case is shown in Scheme Q22a: Br Br Bry/H20 Br / CHCI a OH "Br Scheme Q22a Draw reaction mechanisms (using curly arrows) to explain the different outcomes. (2 x 3 marks) (b) The cis-disubstituted cyclohexane shown on Scheme Q22b undergoes an elimination via an E1 elimination only. E1 but not E2 Br II Br (H3C)3C Scheme Q22b Using the chair conformation provided as a template for your answer, explain why the E2 process is not possible. (4 marks)
