Step 1
Step 1: Analyze the Procedure Review the entire recrystallization process to identify any potential losses that may have occurred during the experiment, such as incomplete dissolution, loss during filtration, or evaporation. Show more…

Your lab partner was unsuccessful at recrystallizing an organic compound from hexanes, even though others in the lab were successful. They want you to tell them what they should do differently next time. They dissolved 1 g of their compound in 100 mL of cold hexane and then heated the hexane to boiling. They then cooled the solution to room temperature, but little to no crystals appeared. How would you change the recrystallization procedure using hexane to significantly increase the percent recovered?

1. After recrystallization, what effects does the presence of any impurity have on the yield? a. A neighboring group recrystallized a pure compound and achieved a 20% recovery. Give two likely causes for their results. For each cause, what could be done to improve the outcome?
