Why is it important to oven dry or flame dry glassware before setting up a Grignard reagent formation or a Grignard reaction? Organomagnesium reagents react readily with water faster than with the desired starting material, lowering the overall yield Water will make the reaction blow up Wet glassware is slippery Too many salts will form in the reaction

In a reflux apparatus, why is it important for joints between glassware to be keck clipped and properly greased? A. To ensure that water does not leak from the condenser. B. It does not matter, as we are not collecting the vapor. C. None of these answer choices are correct. D. To ensure a tight seal to prevent the loss of solvent over the course of the reaction.

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....

Could you help with #2,4,3,6, please
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...

S RROwn as nucleophilic addition. The C-O bond is highly polarized, making carbonyl compounds electrophilic at carbon. If the Grignard reagent reacts with an aldehyde, ketone or ester, the ultimate product is an alcohol. Overall Reaction 0 Br Me PartA Part B Pre-lab questions (15 points) Show the mechanism of the reaction of bromobenzene with magnesium metal in anhydrous diethyl ether There are many inert solvents that could be used but diethyl ether was chosen because it can assist the...

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...
