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...

How would you prepare benzyl methyl ether using a Williamson ether synthesis? The list of reagents to choose from are: 2-Chloro-norborane, Benzyl chloride, 2-Chloro-2-methylpropane, 4-Chloro-1-butanol, and Chlorobutane. I was reading online and it kept mentioning SN2 reactions, using an alcohol, and an alkyl halide for the synthesis. My guess would be using Benzyl Chloride and another one with an OH attached, but I could be completely wrong. Please help and explain by showing the reaction mechanism. Thank you so much!...
