After mixing for three hours, the product is extracted into Dichloromethane and the solvent is removed to give 5.5 g of a yellow oil. Question #31: Using the mmoles of nitrobenzene calculated earlier (45.5) and the molecular weight of the product (157.5 g/mol) predict the theoretical 100% yield of the product in grams. Round to the hundredths place. Question #32: Using this number predict the experimental yield (reminder, the reaction produced 5.5 g of product.) Round to the nearest whole...

As indicated early, the next step of our synthesis will be a Chlorination reaction. Just like before we need to calculate the amount of nitrobenzene we will need. Remember, we obtained 5.6 g of this in the first step. Question #23: Using the molecular weight (123 g/mol) determine the amount of mmol of nitrobenzene. Round to the tenths place. mmol For this reaction to occur, you will need at least one molar equivalents of Cl2 for each molecule of nitrobenzene....

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...
