Lab Experiments

date Experiments to be performed and link to procedure Notes
1/18 Completion of Lab Safety Slides on GA View (deadline Jan 25)

Check-in to lab drawer; intro to lab

Estimation of loss with manipulations experiment

Lab safety slides are to be completed outside of class and lab time.  After lab drawer check-in an overview of the lab will be given and then you will complete the experiment.  A wordprocessed lab report is due at the beginning of the next lab period (1/25)
1/25 Thin Layer Chromatography Wordprocessed report due at beginning of next lab period 2/1
2/1 Distillation of Mixtures The group work performed to compare the different distillations and the analysis written in your notebook and turned in will serve as your report for this experiment.
2/8 Melting Point, Infrared Spectroscopy, and Mass Spectrometry of a solid From 2:30 to 3:00, we will meet to share class results from distillation experiment.  When completed, we will complete this week's unknown analysis lab.

The report for the Melting Point, IR, MS experiment is postponed until we have completed the IR and MS sections of the textbook in class.

2/15 Molecular Modeling- conformations, geometries, surface area, and dipole This may be completed according to your own convenience and you do not need to attend during the normal lab time this week.  I will be present in the 1st floor computer lab during the normal lab time to assist with this experiment, but there are a limited number of computers available in that lab room.  I can also try to help at other times over the next week when I am available.  If you are working in the building and run into trouble on this experiment, you may call the office (706-737-1541) or email me (tcrute@aug.edu) and I might be able to stop by to help.

For your report, for each part summarize results and then briefly identify the trends and rationale to explain the results.  Due at beginning of next lab period, 2/22/12

2/22 Recrystallization Wordprocessed report due at beginning of next lab period (2/29).  Report must address your results with a clear assessment of the quality of your results and estimation of which procedural steps affected your results the most and by how much.  Your overall report should also convey a solid understanding of how key steps in the recrystallization procedure allowed purification of the DMTP in your experiment.
2/29 Steam distillation and product(s) characterization The notebook pages from the pre-lab and the in-lab observations that you have already turned in will be used for the assessment of this experiment
3/7 Enantiomeric analysis of isolated naproxen sodium Wordprocessed report due at beginning of next lab period (3/14)
3/14 Extraction efficiency Late in the lab period it was discovered that one of the solvents that was put out was incorrect!  It was a mixture containing ethyl acetate and not pure ethyl acetate.  Rather than writing a report based on data that used incorrect materials, the notebook pages will be graded instead for the assessment of this experiment.  Nothing further is therefore required.
3/21 Phi Kappa Phi Conference Sessions The undergraduate research conference is being held during our lab time.  Your assignment for lab is to attend one of the science sessions (there are 2 sessions) and write a 1-paragraph summary (wordprocessed please) of one of the speaker's research.  Summaries due at the beginning of the next lab period (3/28)
3/28 Alkene hydration Lab report due at beginning of next lab period- 4/11
4/4 no lab- spring break  
4/11 diastereoselectivity of bromination Lab report due at beginning of next lab period- 4/18
4/18 nucleophilic substitution Notebook carbon copies will used for assessment.  Therefore no formal report for this experiment.
4/25 Chain-growth polymerization of alkenes, Notebook will be used for assessment.  No formal report for this experiment.
5/2  lab checkout, and lab clean up
