Document Summary

The grignard reaction is an orgometallic chemical reaction in which an alkyl, a vinyl or aryl-magnesium halide (grignard reagent) reacts with a carbonyl group in an aldehyde or ketone forming a secondary or tertiary alcohol respectively. As was evident in this experiment, the grignard reagent plays a commanding role in organic synthesis able to form new carbon- carbon bonds. The purpose of this experiment was to synthesize a secondary alcohol compound, diphenyl methanol, using the grignard reaction. Additionally, to understand the underlying mechanism behind the grignard reaction. The melting point and percent yield of the. 1 diphenylmethanol were determined in order to assess the efficiency and accuracy by means of the grignard reaction. In this experiment, bromobenzene, magnesium metal, and anhydrous ether were used to create phenylmagnesium bromide. Phenylmagnesium bromide was used as the grignard reagent, which then was combined with benzaldehyde to form the product diphenylmethanol.
