Q8-(A-H) These are Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learnt in OChem-1 and OChem-ll. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a racemic mixture is formed mark the chiral center with an asterisk () and write "racemic" next to the two structures. All carbon...
