After distilling your crude methyl benzoate, you set aside 5.12 grams of the purified ester. you then prepare the grignard reagent ( phenylmagnesium bromide ) by reacting 2.3 grams of magnesium with 9.45 ml of bromobenzene. you add the 5.12 grams of methyl benzoate to the freshly prepared grignard reagent to form an addition product. finally, after hydrolyzing the grignard addition product, you obtain 5.3 grams of the final product, triphenyl carbinol. what is the percent yield of triphenyl carbinol ? ( the density of bromobenzene is 1.495 g/ml, triphenyl carbinol = 260.33 g/mol, bromobenzene = 157.01 g/mol, mg = 24.3 g/mol )
