The acetylide ion attacks the epoxide, opening up the strained, three-membered ring and creating an alkoxide ion. After the reaction is complete, a proton source is used to protonate the alkoxide ion. In a synthesis, these two steps must be shown separately, because the acetylide ion will not survive in the presence of H30t. Using this information, complete the reaction diagram to propose a plausible synthesis for the following compound using acetylene as your only source of carbon atoms: Soep...
