1. Describe the proper way to transfer solids from a reagent bottle in order to prevent contaminations. (This is a very common problem in student labs. Students rely heavily on their fellow classmates to keep reagents pure for laboratory success.) Using a clean spatula, transfer the solid directly from the stock bottle to your clean, pre-weighed reaction container. You should take only the amount that you need for the experiment, because you cannot return any excess solid back into the stock bottle. Dispose of any unused solids in a proper waste container. Additionally keep the lid of the stock bottle closed when the solid is not being transferred out of it. 2.Draw resonance structures for 9-hydroxymethyl anthracene. It is possible for all three rings to simultaneously have benzene character? 3. Calculate the amount in grams of N-methylmaleimide and 9-hydroxymethyl anthracene that are required in this reaction. 0.1mmol = 0.0001mol of each product 9-(hydroxymethyl) anthracene = 0.001 mol * (208.29 g / 1 mol) = 0.021 grams N-methylmaleimide = 0.0001 * (111.10 g / 1 mol) = 0.011 grams Reference: Chemistry, Department Of.
