IMPORTANT NOTES
Experiment 3: Studying SN1 and SN2 Reactions -- CER REAC 714

Experiment 3 will be carried out in pairs.  But each student provides 
separate prelab, recordings and post-lab.  Only the execution of the labs
is done in pairs.

1. Use Macroscale experiment, starts on page 6.
2. Since you are working in the hood, there is no need to connect a Y-tube
   to your condenser in Section 1 page 8.  There are no aspirators in the
   labs.
3. Section 2, cool flask after refluxing in cold water bath (to speed up
   process).  Pot residue goes in "Unwanted Materials" container.
4. Section 3, no need to transfer sample to a centrifuge tube.  After
   removing as much of the water as possible, dry the product with CaCl2,
   filter through a small cotton plug into a tared container.  Record the
   weight.
5. Omit final (optional) distillation.  
6. You will characterize the product by IR analysis only.  TAs will
   demonstrate.  Water damages IR cells, so the sample has to be DRY 
   (not cloudy) before IR analysis.  
7. TAs will show how to use EPPENDORF micropipettes. There is one
   micropipette for every two students.

Include the following Table in your lab book.  This is the "table"
referred to in the file "grading scheme".
