ОН Н,РО,. H2SO + Н,о Procedure Cyclohexanol (10 g) is weighed into a 50 mL round-bottom three-necked flask, while avoiding getting the liquid on the ground-glass joint. To this is added 2.5 mL of 85% phosphoric acid along with two drops of sulfuric acid (again, avoiding getting the liquids on the joint) and a few boiling stones....

Part A of experiment:
Working in the fume hood, combine 4.0 mL of 10% NaOH solution
and 4 mL EtOH in a 50 mL round bottom flask.
Dissolve 1.0 mL (8.6 mmol) of acetophenone into your
solution.
Add 1.0 mL (9.8 mmol) of benzaldehyde and a magnetic stir bar to
your flask. Clamp the flask
above a stir plate.
Monitor the reaction for 45 minutes by TLC. Acetophenone needs
to be diluted prior to TLC, and
cannot be spotted neat....

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...
