(a)3,3-Dimethyl-4-octyne
(b)3-Ethyl-5-methyl-1,6,8-decatriyne
(c)2,2,5,5-Tetramethyl-3-hexyne

How would you prepare cis-2-butene starting from propyne, an alkyl halide, and any other reagents needed? This problem can’t be worked in a single step. You’ll have to carry out more than one reaction.
Show the terminal alkyne and alkyl halide from which the following products can be obtained. If two routes look feasible, list both.
