In this experiment, a weak nucleophile (2-naphthol) is converted into a strong nucleophile by deprotonation with sodium hydroxide. Then this strong nucleophile, now with a negative charge, reacts with alkyl halide to yield an ether, 2-butoxynaphthalene. 2-butoxynaphthalene is a flavoring agent that has strong fruit smell like raspberry and strawberry.arrow_forwardConvert the alcohol, n-propanol, to n-propyl fluoride in 2 steps.
