Question

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.

Addition: I pyridinium perbromide MW = 320 g/mol Br mp = 236-237 °C 乙 E-stilbene MW = 180 g/mol mp 123 125 °C rLe 2 Elimination: KOH diphenylacetylene MW = 178 g/mol mp = 61 ℃ p = 236-237 °C | triethylene glycol
