After the Williamson ether synthesis was performed, a student obtained 100 mg of crude product. To purify the product the student did a recrystallization: o begin the purification, the student took a 400 ml flask and dissolved a substance in 40 ml of hot water by creating a saturated solution, all of this was conducted on a hot plate. After this, they immedi ut the flask in the fridge and waited for considerable crystal formation. During the last step, the student performed a vacuum filtration by carefully turning the vacuum on, putting a filter paper inside the uchner funnel, and pouring the slurry. After the substance dried, the student weighed the final product, did a 'H NMR and IR experiment and analyzed the spectra. However, the final yield was much low as expected as well as analysis showed a lot of impurities.

![After the Williamson ether synthesis was performed, a student obtained 100 mg of crude product. To purify the product the student did a recrystallization:
To begin the purification, the student took a 400 ml flask and dissolved a substance in 40 ml of hot water by creating a saturated solution, all of this was conducted on a hot plate. After this, they immediately
put the flask in the fridge and waited for considerable crystal formation. During the last step, the student performed a vacuum filtration by carefully turning the vacuum on, putting a filter paper inside the
Buchner funnel, and pouring the slurry. After the substance dried, the student weighed the final product, did a 'H NMR and IR experiment and analyzed the spectra. However, the final yield was much lower than
was expected as well as analysis showed a lot of impurities.
