Tangsiyuan Hua Mohammad Hasani Thursday-11:30-2:2 Synthesis of Triphenylmethanol from Benzophenone and Bromobenzene Abstract： The purpose of this experiment was to synthesize Triphenylmethanol by first producing the grignard reagent phenylmagnesium bromide. Then use the produced grignard reagent to synthesize triphenylmethanol, by reacting with benzophenone and then was protonated by H3O+. Recrystallization was used to purify the triphenylmethanol. The melting point was 161.7oC~162.5oc And
experiment Benzophenone, which is nonpolar and has a polar carbonyl group, was analyzed as partially soluble in methyl alcohol and hexane but insoluble in water. This is because the ketone carbonyl group in Benzophenone will make the molecule slightly polar and thus partially soluble in the intermediately polar solvent methanol and nonpolar solvent hexane due to Benzophenone mostly being highly nonpolar and hexane being nonpolar. However water is highly polar and therefore benzophenone does not dissolve
In Part A, each of the three solid organic compounds were found to be a different polarity. Benzophenone was insoluble in water, rendering it not polar. This compound was also partially soluble in a nonpolar solvent, hexane, but completely soluble in methyl alcohol. Therefore, benzophenone has intermediate polarity. Malonic acid is a polar compound, because it is soluble in water, and biphenyl is a nonpolar compound – it was found to be soluble
