In an experiment, triphenylmethanol is prepared using the Grignard reaction. Reaction of bromobenzene with magnesium in ether produces phenylmagnesium bromide. This Grignard reagent then reacts with methyl benzoate to produce the corresponding alkoxide. Reaction of the alkoxide with aqueous acid then produces the alcohol.  Give a plausible, three dimensional structure for the complex RMgBr-2(C2H5)2O. How do you think the ether molecules are bonded to the Grignard reagent?
