Grignard Reagent Experiment Q1. Benzene is often a by-product in the synthesis of phenylmagnesium bromide. Explain its formation, including a chemical reaction. Q2. If a chemist uses ethanol instead of diethyl ether as the reaction solvent, would the Grignard synthesis still proceed as expected? Q3. What is the structure of the white precipitate that forms when acetophenone is added to a solution of phenylmagnesium bromide? Q4. An aqueous ammonium chloride solution, rather than sulfuric acid, is used in the hydrolysis...

The following GCMS spectrum was of the product of a Grignard
reaction between phenylmagnesium bromide and acetophenone in
anhydrous conditions. The major peak in the chromatogram was
1,1-diphenylethanol. I was able to identify that peak and its
fragmentation. However, I cannot figure out the identity of the
second peak in the chromatogram (around 9 minutes). I have attached
this mass spec in the post below, and I appreciate any help in
determining its identity and fragmentation.

In Grignard reaction:
1) The main by-product of the reaction to
prepare triphenylmethanol is biphenyl. Draw the structure of
biphenyl and write a reaction to explain its formation.
2) Another typical
by-product of any reaction using phenylmagnesium bromide is
benzene. Write a reaction to explain its formation.
