Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
