DISCLAIMER: These handouts provide a “general” outline of the material with practice problems and answers. Each instructor may present the material differently, so not all of the material in the handouts maybe covered by each instructor, and some instructors may cover material not on the handouts. Please review your lecture notes, lecture slides, and online text, and compare them to the handouts to note appropriate topics to work through. The material for the introductory courses (103, 104, and 109) is gradually uploaded during the semester; the material for the organic courses (343 and 345) is available all at once.
Comments, questions, or if you find an error on the handouts feel free to reach out to Tony Jacob at atjacob@wisc.edu
If you wish to provide feedback, there are links available for the organic resources all the time; for the introductory chemistry courses a link near the end of the semester will be provided. We always appreciate feedback so thank you in advance!
