- Thermodynamic vs. kinetic control in the alkylation of chlorobenzene
- Combined spectroscopic identification of an unknown (MS, 1H NMR, IR)
- Aldol condensation-dehydration of unknown aldehydes and ketones
- Acquire and interpret spectroscopic data, including NMR, IR, and GC-MS
- Routine acquisition of 1H NMR and IR spectra following isolation of organic products
- Analysis of 1H NMR data. Applications may include but are not limited to:

- Communicate clearly using the language of organic chemistry
- Maintain complete and accurate records of experimental data and observations
- Prepare written laboratory reports
- Research and present chemical safety and handling precautions (SDS reports)

Representative Text(s) and Other Materials
Mohrig, Jerry, David Alberg, Gretchen Hofmeister, Paul Schatz, and Christina Noring Hammond. Laboratory Techniques in Organic Chemistry: Supporting Inquiry-driven Experiments. 2014.
Although this text is more than 5 years old, it is still in print and is a seminal text that describes laboratory methodology and techniques rather than providing prescriptive activities and is still therefore up to date.
Types and/or Examples of Required Reading, Writing, and Outside of Class Assignments
- Students will conduct a preliminary analysis of experimental procedures with the application of prior knowledge.
- Students will evaluate and reflect on experimental results and summarize their findings in a post-lab report.
- Students will draw their own conclusions based on first-hand observations and discuss them verbally and in writing.
