Question

Type out your calculation and result for the theoretical yield of the cis-dibenzoylethylene synthesis in units of grams. Use the asterisk (*) for the multiplication sign and a forward slash (/) for the division. Below are three HPLC traces from this experiment. The first two are of the pure samples of trans- and cis-1,2-dibenzoylethylene (DBE), respectively. The third one is of the cis isomer that was heated with acid.

Answer 1

The theoretical yield of cis-dibenzoylethylene synthesis requires identifying the limiting reagent, which cannot be determined from the provided information. Hence, it is not possible to calculate the theoretical yield without additional details on the stoichiometry of the reaction.

Step-by-step explanation:

The calculation of the theoretical yield of cis-dibenzoylethylene synthesis starts by considering the limiting reagent and using stoichiometric ratios from the balanced chemical equation that describes the reaction being studied. The stoichiometry of the reaction and the molecular weights of the reactants and products are necessary to complete this calculation. Unfortunately, the provided information does not include a balanced chemical equation or sufficient data to identify the limiting reagent and calculate the theoretical yield of cis-dibenzoylethylene. Typically, one would use the following formula to calculate the theoretical yield: (moles of limiting reagent * stoichiometric coefficient of product)/(stoichiometric coefficient of limiting reagent) * molar mass of product. However, due to the lack of specific reaction details, it is not possible to provide the theoretical yield without further information.
