You are preparing triphenyl carbinol by a grginard synthesis.First you prepare methyl benzoate, and set aside 4.40 grams of thepurified ester for later use. You then prepare the grignard reagent( phenylmagnesium bromide ) by reacting 1.78 grams of magnesiumwith 12.01 ml of bromobenzene. You add the 4.40 grams of methylbenzoate to the freshly prepared grignard reagent to form anaddition product. Finally, after hydrolyzing the grignard additionproduct, you obtain 5.27 grams of the final product, triphenylcarbinol. What is the percent yield of triphenyl carbinol ? ( Thedensity of bromobenzene is 1.495 g/ml ) (molecular weights:bromobenzene = 157, methyl benzoate=136, magnesium =24.3, triphenylcarbinol =260)
