CHEM 51LB Lecture Notes - Waste Container, Benzyl Bromide, Fume Hood
Document Summary
This is the second part of a two-part experiment. Previously, you have reacted one of three possible nucleophiles with benzyl bromide in the presence of sodium hydroxide to produce a solid product. In this lab period you will purify the product using recrystallization and identify it and, therefore, your unknown nucleophile via melting point and thin layer chromatography (tlc). Additionally, you will analyze the saved aliquot of your filtrate for the presence of reactants, product, or products of side reactions. Technique 14: melting points and melting ranges in techniques in organic. Technique 15: recrystallization in techniques in organic chemistry 3rd ed. pgs. Technique 17: thin-layer chromatography in techniques in organic chemistry. Follow the instructions in the 51lb report & presentation guidelines document located on the course website to prepare your pre-lab. Ethanol, hexanes, and ethyl acetate are volatile, toxic and flammable. Immediately set aside ~20mg of your crude product for later.
