Organic Chemistry Lab I (CHEM 237) Experiment 10: Phase Transfer Catalysis 100% Correct List the procedural steps, from start to finish, that are required to convert 2-naphthol and allyl bromide into allyl 2-naphthyl ether. The reaction is performed on a small scale by mixing the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial. Sodium hydoxide (base) is added to initiate the reaction. The reaction flask is covered and stirred to conduct reaction to prevent evaporation...
