Synthesis of Triphenylmethanol Used Bromobenzene + anhydrous diethyl ether and magnesium turning to make phenylmagnesium bromide.  Used Benzophenone with phenylmagnesium bromide to synthesize Triphenylmethanol Question: discuss the formation of the two main byproducts (biphenyl and benzene) and potential problems associated with the Grignard reaction (water-free conditions, fresh active magnesium, concentration of the solution, unreacted starting material)

Chemistry What are the stereo-chemical results of reduction that are theoretically possible for benzil?   Also explain the stereo-chemical relationships of the isomers of hydrobenzoin.

what is the purpose of adding concentrated sulfuric acid to a product after distillation? what products would you expect to be produced if H2SO4 were used as the acid catalyst, and an equimolar mixture of NaCl and NaBr were used as the sources of nucleophiles?  Based on the previous question: more than one product is actually produced. Will the products be produced in equal amounts. why or why not
