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 1. Draw your complete reaction, including the formation of the Grignard reagent and the reaction with your carbonyl compound. Below each reagent, write its molecular weight and density (if a liquid). Also write how much of each material you will use in ml (if liquid), grams, and moles. Also include the molecular weight and melting point of your final product. 2. How many moles of Grignard reagent are you synthesizing? What mass of water could fully react with...

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...
Prelab questions:1. Make sure the reaction table described above is completed in your notebook.2. Two benzaldehyde molecules combine with one acetone molecule in this aldol reaction. If someone uses 5.0 mL of benzaldehyde and 2.5 mL of acetone to try to improve the yield of product, is this the correct ratio of molecules so that there is no excess? Why or why not?The Aldol Reaction: Synthesis of DibenzalacetonePurpose: Introduce the student to the hands-on chemistry of carbonyl condensations.Warning: Dispose of...
