Question

"a reaction was performed in which 0.57 g of 2-naphthol was reacted with a slight excess of 1-bromobutane to make 0.32 g of 2-butoxynaphthalene. calculate the theoretical yield and percent yield for this reaction."

Answer 1

Convert 0.47g 2-naphthol to mols. mol = g/molar mass.
Using the coefficients in the balanced equation, convert mols 2-naphthol to mols 2-butoxynaphthalene then you have to Convert mol 2-butoxynaphthalene to grams. g = mols x molar mass. This is the theoretical yield.
