A study of the structure of organic compounds and of the influence of structure upon the chemical and physical properties of these substances. The following topics are emphasized: hybridization, resonance theory, spectroscopy, stereochemistry, acid-base properties and nucleophilic substitution reactions. Periodically, examples will be chosen from recent articles in the chemical, biochemical, and biomedical literature. Laboratory work introduces the student to basic laboratory techniques and methods of instrumental analysis. Each laboratory section is limited to 20 students. In the fall, sufficient sections will be added to meet total enrollment. The spring semester is limited to two laboratory sections. Three hours of lecture, one hour of discussion section, and three and one-half hours of laboratory per week.

In fall 2020, Chemistry 221 will be taught remotely. Lectures, discussion sections, and laboratory sections will be held synchronously and will also be recorded for asynchronous learning. All course resources will be posted and organized for ready access on Moodle. A class calendar will be continually updated with important dates and reminders. The interactive program Mural will be employed for group exercises, and submitted work will be graded through the Gradescope interface. Both written and recorded answer keys will be provided for all discussion section problems, and recorded answers to “one-minute sheet” questions submitted by students after each lecture will also be provided.

Requisite: CHEM 161 or CHEM 165.

Fall semester: Professor Hansen, Visiting Assistant Professor Lopez and Lab Manager Reutenauer. Spring semester: Visiting Assistant Professor Lopez.
