Resumen
Oxidation-state and donor−acceptor concepts are important areas in the chemical education. Student worksheets containing problems that emphasize oxidation numbers, redox reactions of organic compounds, and stoichiometric reaction equations are presented. All of the examples are incorporated under one unifying topic: the production of vicinal dibromides. Recent synthetic approaches use redox systems to generate bromine in situ to minimize hazards associated with molecular bromine. They illustrate how a range of oxidants can be applied to brominate the alkenes. The oxidant Oxone, also called Caroat or Curox, is examined. In addition to the solutions, the worksheets contain supporting information to help the students solve the problems. Thus, students are able to work independently with the material.
