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...
