Summary

1 / 6

Past student reviews · Tehshik Yoon, Barbara Whitlock

The class was not easy, though one student felt having a great professor helped. Another found exams really hard, specifically mentioning reaction mechanisms, though they appreciated the instructor's slow pace and openness to questions.

What you’ll be able to do

  • Use spectroscopic data to elucidate chemical structures and analyze samples of pure and impure mixtures.

  • Safely use basic organic chemistry apparatus, glassware, and techniques for the synthesis, isolation, and purification of organic molecules.

  • Obtain and use computational data to support their analysis of a molecular structure and/or reaction outcome.

  • Use the electronic and molecular structure of organic molecules to predict and rationalize chemical reactivity.

  • Construct and use a reaction energy profile to justify why a particular reaction system is likely to produce the product formed most quickly or which is most stable with an emphasis on the reactions of alcohols, alkyl halides, aromatic compounds, and carbonyl-containing compounds.

Student experience

the class

Past student reviews · Brian Esselman

Students found the class pretty good, with Brian Esselman setting high expectations while trying to be helpful. One student described exams as nothing crazy, while another noted the professor wanted you to learn the material rather than just get a good grade.

Recent recorded grades — Spring 2025: 3.23 GPA, 46.1% A/AB (n=508 letter grades); Fall 2025: 3.23 GPA, 46.3% A/AB (n=369 letter grades); Spring 2026: 3.21 GPA, 46.8% A/AB (n=575 letter grades).

Approximate 80% prediction interval

About this estimate

The course’s semester-average GPA, not an individual student’s grade. The center uses 5 same-season terms, weighted toward recent results.

The range uses the finite-sample 80th-percentile rank of absolute errors from earlier same-season forecasts. Each forecast uses only records from earlier terms. At least four forecasts are required; bounds are rounded outward and limited to 0–4. This is an empirical estimate: changing instructors or grading policies can reduce its coverage.

About this comparison

1280 courses over the same term, each with at least 30 recorded letter grades. Cross-listed courses count once. GPA is not a measure of difficulty or teaching quality. The typical course is the median by recorded grade count; tied values are not counted as lower. Grade counts describe course scale, not unique students or typical section size.

Descriptions compare GPA with this group’s average: at least 0.20 higher or lower; otherwise close to average. Section size uses median recorded enrollment: small up to 30, mid-sized 31–99, large 100+. Lectures and discussion/lab sections are described separately.
