• Resumen

  • A new two-step experiment has been designed and developed for the curriculum of the Organic Chemistry Laboratory 2 (CHEM2240L) sophomore course at Xavier University of Louisiana, in New Orleans. Initially, cyclohexanol was converted to cyclohexanone using bleach as the oxidizing agent followed by the formation of the cyclohexanone oxime. However, there were several problems such as reaction monitoring and product analysis associated with this chemical procedure. To improve upon and resolve those problems, we developed these new procedures by changing the substrates from cyclohexanol to 9-fluorenol, a few reaction conditions, and the method of analysis. The experiments were implemented as part of the curriculum in Fall 2019 and Spring 2020, and while performing this new two-step experiment, students were able to see the reaction progress successfully. The procedure and the execution of these experiments will be discussed here.
