Reagent Calculation
- Before coming to class, you will need to calculate how much of
the phenylmagnesium chloride solution will be needed for your
reaction. You should calculate for 2.0 equivalents of
Grignard reagent based on how much benzophenone you are to use in
the reaction.
- 2.0 M in THF of phenylmagnesium (2 eq)
- benzophenone = 0.120 g
Please help me figure this out! I keep getting the wrong answer. Professor said it should be 0.658 mL but I'm getting 0.3197 and not sure what I am doing wrong.

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....

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...

Product Isolation After stirring the reaction for 5 minutes and allowing the reaction mixture to cool (the reaction can be exothermic), remove the Claisen head from the conical vial. Slowly add 3 M HCl(aq) drop-wise. The solid may need to be broken up with a stirring rod or a pipet. Continue to add acid until the aqueous phase (bottom layer) tests positive with pH paper. Extractions can be done using the conical funnel...
