Phenylmagnesium bromide, generated by stirring 26.7g of bromobenzene and 3.9g of freshly cut magnesium in tetrahydrofuran, was added to a 12.0g ethyl benzoate solution in 30mL THF. After refluxing the reaction and subsequent workup, triphenylmethanol was produced. a. Determine the equivalents of each reagent compared to the primary reagent (ethyl benzoate.) b. Determine the percentage yield of the reaction if 19.0 g of the product were obtained.
