Question

need to check answers; Acetylene is an important synthetic building block that can be used to produce organic compounds with a wide variety of other functional groups. Consider the transformation of 3-phenylpropanal from acetylene shown below, which requires several steps.

Part 1; image 

part 2 : The first step in this synthetic sequence involves an alkyne coupling reaction. Acetylene is deprotonated, and the acetylide anion is reacted with an organic halide. Draw the structure of the halide required in this step.
