A Grignard reaction was performed using the following steps: Step 1: Addition of Grignard Reagent: Phenyl Magnesium Bromide a solution of phenyl magnesium bromide (2.7 mL of a 3.0 M solution in anhydrous diethyl ether) and 5 mL of anhydrous diethyl ether was dispensed into the round-bottom flask and stirred with a stir bar. Step 2: Addition Formation: Reaction with Benzophenone A solution of 0.72 g (mp = 48-49 degrees C) of benzophenone and 2.0 mL of anhydrous diethyl ether...

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)

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
