Use the following atomic weights and quantities to calculate the overall % yield of dibenzyl ketone. Remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. For problems not involving a one to one stoichiometry it may be easier to calculate the theoretical yield in grams from both reagents to determine which is truly the limiting reagent.

What is the overall % yield of triphenylmethane from benzophenone given the 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. 66% 70% 62% benzophenone → benzopinacol → benzopinacolone triphenylmethane Answer:
C4H6O3 + H2NC6H4OH = C8H9NO2 + CH3COOH Calculate the percent yield for this acetaminophen synthesis. Hint: This is a limiting reagent question. You'll have to calculate the theoretical yield of the product before you can find the percent yield. We started with 0.321 g of 4-aminophenol. At the end of the reaction, the product weighed 0.180 g.

I'm not sure how to go about calculating for percent yield of my product. Do I need to calculate theoretic yield first? I always mix up the formulas. I was performing the horner wadsworth reaction , synthesis of 3,4-Methylenedioxystilbene. The reaction was between diethyl benzylphophonate and 3,4-dimethylenedioxybenzaldehyde. Aliquat 366 was the catalyst.

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 dibromide is the limiting reagent for the synthesis of diphenylacetylene; what is the overall % yield of diphenylacetylene from benzaldehyde given the 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. 52% 87% benzaldehyde → stilbene → stilbene dibromide 41% Answer: 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…
