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...

Write a reaction showing how benzyltriphenylphosphonim chloride (PhCH2PPh3Cl, Wittig salt) is prepared from benzyl chloride (PhCH2Cl).
Here is a molecule. Being asked to do a retro synthesis (reaction scheme) on the molecule and go all the way back to produce the molecule until I can't go back anymore (think benzene or carbon). I can use any source and synthesis/reaction to produce the molecule above. Some notes about the molecule: Here is my answer so far, I need help! Please help, using my answer above here is what I noticed: > Some steps can be omitted and...
