Unlike chemistry textbooks printed on paper, this webbook is able to contain dynamic Synthlet and Database pages that explore and make predictions about aspects of chemical structure & reactivity.

Thanks go to the authors of web sites linked to from these pages and to the many members of the ChemEd internet discussion list who have answered my many questions and synthesized such interesting postings.
