What trend (if any), was there for the % yields of ferrocene, acetylferrocene, and diacetylferrocene based on whether the reaction was done in a conical vial or round bottom flask?

Mass of total crude product isolated: Mass of product placed on column: .5g Mass of ferrocene recovered: 0g Mass of acetylferrocene: .25g % yield of acetylferrocene: Mass of diacetylferrocene: 0g % yield of diacetylferrocene: When only a portion of the product mixture is purified, the percent yield for the total reaction cannot be found, but can be estimated. The calculation requires that you make the following assumption: the portion of crude product you purified is representative of the whole. If this is true, then you can assume that if you isolated 0.1 g of acetylferrocene from a 0.5 g sample being purified (20%), then the original total crude product should also have contained 20% acetylferrocene. Use this theory to calculate the mass of a product which would have been present in the total crude mixture. Now compare this to the theoretical yield to establish your estimated % yield. Show calculations on a separate paper.

Balanced chemical equation: 2 Ferrocene + 2 Acetyl Chloride → AlCl3 → Monoacetyl ferrocene + Diacetyl ferrocene. 3. Assuming that your reaction has produced both monoacetyl and diacetyl ferrocene, calculate the theoretical yield and percent yield for the pure monoacetyl ferrocene product. Show all stoichiometric calculations with appropriate formulas.
