Lab Report
#2
Purpose:
 |
Provide an opportunity to write a laboratory report
results and discussion sections
|
|
Provide an opportunity to analyze NMR and GC-MS data
for our own experiment
|
|
Provide an opportunity to analyze the combined
results for the entire class' experiments in order to determine the
factors that affect the competition between the SN2 and E2 reaction.
(Experiment 6 from the lab manual)

Results:
Reporting of NMR and GC-MS Data from your own experiment:
As you may recall, each group of students is responsible for
analyzing their own NMR and GC-MS data in order to determine the
outcomes from their reaction. It is, therefore, your
responsibility to report your data from your experiment. This
includes a reporting of NMR data in tabular form (see lab manual) and
GC-MS in tabular form including retention time, observed mass, and
purported identity. From this data a relationship between the
amount of SN2 versus E2 product must be reported. You need to
prove that you have the compounds you say you have.
Reporting of Class Data for E2 vs Sn2 outcomes.
Since the major goal of the lab was to determine the factors that
affect the competition between Sn2 and E2 reactions, it is important
that you report this data. Tabular results would be the most
appropriate. Ensure that all data is in the exact same format so
that analysis can be easily accomplished. State where this data
came from. It may be important to make any important notes about
the validity of the data.
Discussion
Analysis of Class Data for E2 vs Sn2 outcomes
The main part of your experiment will be based on explaining the
groups collective data. Why did some reactions give only one
product and other give mixtures? What factors affect the
distribution between Sn2 and E2? This is where you discuss the
meaning of all the data.
It may be appropriate to further elaborate on the data in terms
of validity and need for further experiments.
This Lab Report is due no later

Please also turn in your lab notebook and spectral
notebook at this time.
