1) Propose a mechanism for the following two-step transformation. Be sure to include all curved arrows, intermediates, and by-products. (5 marks) Br -OH 1) NaOH, HO 2) HBO Br OH 2) Propose a synthesis for the transformation below. You may use any reagent discussed in the course notes or textbook, as well as any additional compound with 2 or fewer C atoms in your solution. (5 marks) هر
1) Choose one molecule from the set and create an 8-step synthesis scheme using the chosen molecule as your starting material. You need to write the complete set of reagents and draw the product expected from each step. Reagents typically used together are considered one step, eg. 1) LAH 2) H.O should be considered as one step Your 8 steps must include at least one reaction from each of the chapters, aldehydes and ketones, carboxylic acid derivatives, alcohols. You can...
