Using the starting material(s) on the left as the only source(s) of
carbons in the final product and any other organic or inorganic reagents, show how to synthesize the molecule on the right. You must show all molecules synthesized along the way and the reagents needed for each step. Do not show mechanisms. You may use abbreviations found in the book or class notes, for example, t-BuOK. READ THESE INSTRUCTIONS AGAIN and be sure you understand them.
(all carbons must come from the ethyne; it can be used more than once)
