MSISTRY 203-204 Grganic Chemistry Lab Manual 3 4 EXPERIMENT #9 The Preparation of t Butyl Chloride A tertiary carbonium ion is more rapidly formed than a secondary or primary carbonium ion. Once formed, a tertiary carbonium ion is stabilized by charge dispersal to a greater extent than a secondary or primary carbonium ion. It therefore has a longer life expectancy. Primary carbonium ions, protons, may exist in solution only in solvated form have any free existence, they dehydration reaction and...

EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...

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...
