Select four (4) of the followings synthesis (A to F) to show the steps required to form the specific product using Acetylene as starting reagent. Include the reagents need it to complete each step and the intermediate products. (Hint: Consider to use the road map chart for all the reactions cover until chapter 9 and drawa retrosynthesis analysis to help you to find the appropriate steps in each synthesis.)
