The course demanded significant time, including two multi-hour labs weekly and lengthy postlab reports. One student found the grading criteria on these reports confusing and difficult to navigate.
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.

Raw average: 4.26/5 from 162
quality ratings. The adjusted rating blends this with the UW review average
(3.66/5), weighted as 20
additional ratings. Smaller samples stay closer to that average. Each
captured review is counted once in the prior; this does not correct who
chooses to leave a review.

Past student reviews · Brian Esselman
Brian Esselman teaches a demanding course with 2+ hour labs and 5+ hour postlab reports. Students found him approachable, though some criticized the disorganization, TAs giving wrong answers, and reliance on old videos. Exams were manageable for those who stayed on top of the material, but lab grading criteria were sometimes confusing.

Historical instructors & teaching patterns
Past student reviews · Barbara Whitlock, Ieva Reich
Historical students found the material extremely difficult, with one describing exams as really hard while another noted the content was challenging but taught well. Barbara Whitlock went slow and was open to questions, whereas Ieva Reich was praised for her teaching ability despite the material's inherent difficulty.

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+.
