Unformatted text preview: bromobenzene at one time. The actual melting point of triphenylmethanol is 163 ºC. Our product’s melting point is significantly lower than this melting point, which shows the presence of impurities. That could have been caused by adding too much bromobenzene at one time, not warming the solution adequately, etc. Although we only were able to produce a small amount of crude product, we efficiently recrystallized it and determined the melting point and percent yield (even though our product was obviously impure). Questions: Write a balanced equation for the reaction of phenylmagnesium bromide with water. Provide a synthesis of triphenylmethanol that uses a Grignard reaction and does not start with benzophenone....
