Question 10: What technique should Gwen use to collect the final product that forms?

gravity filtration

reflux

vacuum filtration

rotovap

Na OCH3 N. ??? N. Gwen set up the reaction shown above. She started with 1.5 g of the p-acetamidophenol and added exactly 1.0 molar equivalents of the sodium methoxide. Her solvent was ethanol (100%). After letting the mixture stir for 10 minutes, Gwen then added 1.3 molar equivalents of the alkyl bromide. She let the reaction heat at reflux for 30 minutes, then slowly cooled it to room temperature. During the course of the reflux, she noticed that a white solid formed until it there was enough to coat the sides of the flask. After the solution was cooled, she added 10 mL of water to the reaction mixture. When she did that, the solid disappeared. Next, Gwen cooled the mixture on ice. A different solid (one that looked like shiny glitter) appeared during the cooling process.
