1. Define the term "Nucleophile" and explain how a Grignard reagent acts as a nucleophile. Briefly explain using a chemical equation, why it is necessary to use dry apparatus and reagents during the synthesis of C6H5MgBr. phenylmagnesium bromide. 3. By referring to a textbook, write a mechanism for the reaction between phenylmagnesium bromide and the ketone butanone. In a reaction of phenylmagnesium bromide with butanone the Grignard reagent was prepared from 25 g of...

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...

Preparation of Triphenylmethanol Using the Grignard Reaction.
RH ROOH CO TO R-R MgBr 1.ether 2.11-SO/10 Icther Grignard reagents are highly reactive and can undergo undesirable RCOH TH₂O side reactions if impurities such as water, carbon dioxide, or oxygen are present. If the organohalogen is added to the R-Mg-X magnesium too quickly, undesired coupling reactions can also occur. In this experiment, you will use 0.015 moles of either benzophenone or ethyl benzoate as the recipient of the phenylmagnesium bromide and this...
