Need help please explain, thank you.
Question 10 Not yet a s w ed Marked out of 1.00000 P Flag question Assuming that benzaldehyde is the limiting reagent for the synthesis of stilbene, that stilbene is the limiting reagent for the synthesis of stilbene dibromide, and that stilbene di percentage yield of each step of the reaction sequence as follows? Give only two significant digits. If the answer is a whole number with two digits, do not include the decimal. o ide is the limit ng reagent for the synthesis of diphenylacetylene; what is the overall % yield of diphenylacetylene from benzaldehyde given the 63% 68% 32% benzaldehyde â stilbene â stilbene dibromide â diphenylacetylene Notes: For our multi-step synthesis we cannot just calculate the yield based on starting amount of benzaldehyde and final amount of diphenylacetylene because your group may have been supplemented with commercial material at one or more steps In truth most chemist use an excess of the least expensive reagent to increase their yield. So in our case benzyltriphenylphosphonium chloride should probably be our limiting reagent Answer: Previous page Finish attempt
