  1. Organic Chemistry Laboratory Notebook Maintenance

  2. Before coming to class… • Review the POWERPOINT presentation on the course website for the experiment. • Complete PRE-LAB assignment section of laboratory notebook. • Remember, without a COMPLETE PRE-LAB assignment, you will not be allowed to do experiment!

  3. Pre-lab Assignments • Located at the end of the POWERPOINT presentation for each experiment! • Pre-lab and in-lab notebook entries vary depending on experiment.

  4. Step 1:Complete Information at top of page Experiment title and number Date 1. Structure, Intermolecular Forces, and Solubility 8/8/08 Name Course Section Lab partner Jane Doe 211 M 11 Joe Doe Give lab day and time here

  5. Step 2:Objectives • Always include a header. • Give brief description of what you are attempting to do and how you are going to do it. OBJECTIVE: To investigate the relationship between molecular structure, intermolecular forces and solubility of various organic and aqueous solvents using solubility testing.

  6. Step 3:Table of Physical Data • Prepare a single, organized table including physical constants and hazards for all chemicals in list as instructed. • Physical data is available from MSDS sheets! (see WWW Links on course website). • WIKIPEDIA IS NOT AN ACCEPTABLE SOURCE!

  7. Step 3:Finding Physical Data • Can use one of three sites… • http://hazard.com/msds • http://sigmaaldrich.com/unitedstates • http://www.chemexper.com/

  8. Step 4:Reference to Procedure • You are responsible for reading the procedure thoroughly before coming to lab, however only need to reference the procedure and the manual from which it came in the PRE-LAB portion! Experimental Procedure  (from CHML 211-212 Laboratory Manual for Organic Chemistry, Fall 2010 , Seaton and McCreery , p. 7) full name of manual, publication date, and authors, and page number of procedure!

  9. Step 5: Day of lab… • Your lab instructor will initial the pre-lab portion of your lab notebook prior to the lab briefing. • Without a COMPLETE pre-lab, you will NOT be allowed to perform the experiment.

  10. Step 6: During the lab… • Note the list of requirements for the experiment. • Write information down in notebook as you do it, not after you leave the room! • DATA/CALCULATIONS • Record which unknown was used • Record distillation range of each fraction collected • Record GC vial slot number for fraction #1 • Record GC vial slot number for fraction #4 • Record GC sample solvent used • Show one EXAMPLE of an adjusted area percent calculation

  11. Step 7: During and after the lab… • EXPERIMENTAL PROCEDURE • In paragraph form, briefly describe the procedure that you actually followed during the lab. • Paragraph must be written in PAST TENSE, PASSIVE VOICE. • Include any mistakes, accidents or observations if necessary. • Each student will submit their own typewritten copy of the procedure as performed in the lab. • This written procedure should be based on what you actually did, not what the lab manual told you to do (YOUR story, not mine). • This procedure will be due along with any lab notebook pages along with the final lab report.

  12. Step 8: After the lab… • Remove the YELLOW lab notebook pages containing all pre-lab and in-lab entries for the experiment and attach them to your FINAL LAB REPORT for grading.
