The Synthesis of Triphenylmethanol via a Grignard Reagent
In this experiment, the organometallic regent, phenyl magnesium bromide, a Grignard Reagent, was reacted with benzophenone and hydrolyzed to synthesize triphenylmethanol. The final product, triphenylmethanol, was weighed and the melting point and percent yield were determined. The limiting reagent in the reaction was benzophenone. The melting point measured was between 153 degrees Celsius and 157 degrees Celsius. The literature value for the melting point of the product is 164.2 degrees Celsius. The percent yield determined was fifty-nine percent. Although, the melting point is close to the literature value, it can be determined that there are impurities in the product. These impurities could be a result of the byproduct biphenyl, which occurs when two phenyl radicals combine during the synthesis of the Grignard Reagent, or because of the presence of water in any of the reaction tubes, which destroys the......
