Make at least four (4) synthesis problems with 4 steps or more. Use addition, substitution, and elimination reactions. Try to change the location of substituents or of pi- bonds, and to change the substituents. Have at least one synthesis that uses ALKYLATION of an alkyne to increase the C-C skeleton. Format each synthesis as a problem and a solution as shown below:GA 11 example problem.pdf
