Post-lab Questions: 1. Explain/show how conjugation of a double bond with a carbonyl affects the vibrational frequency of the carbonyl. How was this demonstrated in our specific system? The melting point of the material from part A was lower than the expected 204 'C for the anti- addition product but significantly higher than 95 'C, the melting point of the...

These questions are about a lab on Grignard Reactions 10. (3) If you had done this reaction in the lab, you would have added the Grignard reagent to a carbonyl containing molecules such as the ones from question 3. After addition the reaction is usually opaque and forms white precipitate, what is the precipitate made of? In other words, what are the salts that form? 11. (3) After these salts have formed, the reaction is quenched with acid, 5 N...

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...
