Organic Chemistry Laboratory Notebook

Maintenance

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!

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.

Step 1: Complete Information at top of

1. Structure, Intermolecular Forces, and Solubility 8/8/08

Jane Doe 211 M 11 Joe Doe

Give lab day and time here

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.

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!

Step 3: Finding Physical Data

• Can use one of two sites…

– http://hazard.com/msds

– http://www.chemexper.com/

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!

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.

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

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.

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.
