A Discovery-Based Hydrochlorination of Carvone Utilizing a Guided-Inquiry Approach To Determine the Product Structure from ^sup 13^C NMR Spectra

This experiment describes a discovery-based method for the regio- and stereoselective hydrochlorination of carvone, appropriate for a 3-h second-semester organic chemistry laboratory. The product is identified through interpretation of the ^sup 13^C NMR and DEPT spectra are obtained on an Anasazi EF...

Zusammenfassung:This experiment describes a discovery-based method for the regio- and stereoselective hydrochlorination of carvone, appropriate for a 3-h second-semester organic chemistry laboratory. The product is identified through interpretation of the ^sup 13^C NMR and DEPT spectra are obtained on an Anasazi EFT-60 at 15 MHz as neat samples. A guided-inquiry approach is used to aid the students with the interpretation of the NMR spectra. [PUBLICATION ABSTRACT]
