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
electrophile , to form a chemical bond (James). The nucleophile that will be used is phenylmagnesium bromide. They react with aldehydes to form secondary alcohols or react with ketones to form tertiary alcohols. Since benzophenone is a ketone, a tertiary alcohol will be formed. Benzophenone is the electrophile. A Grignard reagents is important to organic synthesis and can be easily prepared using an organic halide, turnings, and an ether solvent Weldergirma). Grignard reagents are also strong bases and
