Question 2 (a) Show how the Wittig reaction might be used to prepare the following alkene. Mechanisms are not required, however your answer should identify what carbonyl component would be used, and show all steps and reagents required to prepare the necessary phosphorus ylide from the appropriate alkyl halide. You should also justify the resultant stereochemistry observed. HH [6 marks] c) wine celor de (b) What product would you expect from the halohydrin reaction shown below? Provide a mechanism for...
