How would you calculate % yield of intermediate A and the
final product diphenylacetylene? The mass of intermediate A
collected during the experiment was 74 mg and the mass of the
crystals (diphenylacetylene) was .162 g which is not feasible
however it is due to error as the filter paper wasn’t completely
dry yet. Included are pictures of all the chemicals used as well as
the procedure so you can see what was added to the reaction.

After performing dehydrobromination of meso-stilbene dibromide,
why did we have to heat the reaction to such an extreme
temperature? And what is the slow step in this reaction - first or
second? Why?

In this experiment, you will react the product you made in last week's experiment (meso-stilbene dibromide) with strong base in an elimination experiment. This reaction with yield an alkyne, diphenylacetylene. The strong base you will use is potassium hydroxide. The second step...
