Workbook for Organic Chemistry

Great source of basic and advanced problems in organic chemistry.  Chapters are divided by functional group or topic, such as stereochemistry or NMR.  Each chapter has problems that are categorized as general reactions, syntheses, or mechanisms.  Answers are provided in a separate section.  These are GREAT exam problems.  I do not inform my students of this text (because I want to be able to use it as a source of exam questions), but it would be an excellant resource for students looking for more problems to solve.
