These questions is based on Grignard Synthesis of Malachite Green A) You are directed to polish the magnesium turnings. What's the purpose of doing this? Specifically, what is removed by polishing? B) Why are we being so careful to eliminate moisture from the reaction vessel, solvent, etc? What is the reaction that will occur if water is present? C) If the Grignard reagent doesn't seem to be forming, you are directed to grind the mixture a bit using a flat-headed stir rod. Why/how might this get the reaction started?
