I did a lab for organic chemistry and now need help completing the elimination reaction lab report form (attached). Just fill out the Elimination report form in the document I attached. I have also included other class data for reference.

CHEM 308 Elimination REPORT SP17
NAME ______________________________________
Several responses below require information to be taken from your pre-lab notebook. Remember that you must cite verbatim. You may supply corrections
and/or add additional information for partial credit consideration ONLY if you explain that the information you have provided is not in your notebook.
4. Explain how the structure of the alcohol (and thus the alkoxide base) affects the quantity of 1-heptene and 2-heptene
products formed. You must compare the results from your alcohol to the class results for the other alcohols. To
support your answer, correlate the size of each alcohol (alkoxide) used with the ratios of areas of 1—heptene to 2heptene (cis + trans together) and include actual numerical ratios. (4 pts)
5. From the class experimental results, determine if the size of the alcohol (alkoxide) used in the lab effected the ratio of
trans-2-heptene to cis-2-heptene. To support your answer correlate the size of each alcohol (alkoxide) used with the ratios
of areas of trans-2-heptene to cis-2-heptene and include actual numerical values. (3
6. Explain how the structure of the alcohol (and thus the alkoxide base) affects the formation of the SN2 product.
Compare the presence or absence of these products in the spectra of all of the alcohols used in lab to support this
explanation (4 pts).
7. Did your reaction go to completion? How do you know? (2 pts)
