Presume that you need to prepare 4-methyl-2-pentyne also discover that the only alkynes on hand are acetylene and propyne. You as well have available methyl iodide, isopropyl bromide, and 1, 1-dichloro-3-methylbutane. Sketch an efficient synthesis using any or all of the mentioned reagents to form the 4-methyl-2-pentye.
