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...

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...

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.

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....

The following synthesis is done in 3 steps.
1. The selective oxidation of alcohols.
2. Aromatic Grignard
3. Carbon-Carbon coupling.
Perform stoichiometric calculations to obtain 1 ml of
the final product, using the concept of limit reagent in the
synthesis of geranial and phenylmagnesium bromide. assuming 100%
yield.
The complete equations of the synthesis of geranial and
grignard reagent are shown below. (They are needed to calculate the
