Assume that we ran this reaction with 1.0 g Mg, 4.5 mL bromobenzene, and 2.3 mL methylbenzoate. If you got 2.15 g of product calculate your percent yield for this reaction.
1. Write a detailed mechanism for the reactions of phenylmagnesium bromide with methyl benzoate which produced the conjugate base of triphenylmethanol. 2. Assume that we ran this reaction with 1.0 g Mg, 4.5 mL bromobenzene, and 2.3 mL methylbenzoate. If you got 2.15 g of product calculate your percent yield for this reaction. (just do number 2 please)

Using the reaction shown below, calculate the percent yield obtained by a student when reacting 5.0 g of 3-methoxysalicylic acid with 3.9 mL of iodomethane in the presence of 10.3 g of potassium carbonate and obtaining 4.5 g of product, 2,3-dimethoxymethyl benzoate. You should determine which of the three reactants is the limiting reagent and the theoretical yield first.1a page 1.jpg
