Starting with acetylene use a sequence of reagents to show how you could make each of the following products. Note that some steps will be redundant so please just start from a common intermediate once you have shown its synthesis. For example, all of the other products can be made from either 1-butyne or 2-hexyne. You may not use any other source of C other than methyl bromide, calcium carbide, chloroform and the products you can make from these sources....
