Scenario: You are responsible for preparing 2-butoxynaphthalene, a flavouring agent that has a strong raspberry taste. You look up the procedure for the preparation of your target compound and find the following: Sodium hydroxide (0.560 g) is added to a solution of 2-naphthol (0.995 g) in ethanol (14 mL) and the solution is heated to reflux. Once both the sodium hydroxide and the 2-naphthol go into solution, the 1-iodobutane (1.00 mL) is added slowly. After 15 minutes, the reaction mixture...
