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
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
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
