We used "dry" dichloromethane this week, where all water was removed from solvent by first adding a chemical absorbent then distilling the solvent. Why did we need to ensure no water was in the reaction? Choose TWO of the following that are true. (hint: think about the reaction mechanism and what could happen if water were present) water could behave as a nucleophile and perform a "hydrolysis" reaction on pthalic anhydride, so the intended reaction would not proceed water would decompose the catalyst, so the intended reaction would not proceed water would behave as an electrophile and would be attacked by p-xylene, so the intended reaction would not proceed even a little water would lower solubility of reactants dramatically
