The synthesis of triphenylmethanol via the grignard reaction is
given by the following equation (below):
A student decides to perform the above reaction. She starts with
200 mg of bromobenzene (M.W. = 157) and uses 45 mg of Mg (M.W. =
24.3) and 0.36 g of benzophenone (M.W. = 182).
a. Calculate the limiting reagent
b. Calculate the theoretical yield of triphenylmethanol (M.W. =
260.3)

Draw an arrow pushing mechanism and find the theoretical yield
for the Grignard reaction below using the following amounts of
reagent with the given molecular weights:
565 microliters of 2-bromopropane (molecular weight =
123g/mol)
304 microliters of 4-methoxybenzaldehyde (molecular weight =
136.15g/mol)
molecular weight of product = 180.27g/mol
The
limiting reagent is _____________.
In this experiment, you will prepare the Grignard reagent isopropyl-magnesium bromide from 2-bromopropane. You will allow this Grignard reagent to react with 4-methoxy-benzaldehyde to form a secondary...

What is the theoretical yield (in grams) and percent yield of your
triphenylmethanol product in this experiment? (Weight of
triphenylmethanol: 0.060g)
BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...

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 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....
