Scaffolded Structure Determination Activities Utilizing 2D NMR Spectroscopy of Simple Organic Molecules
Journal of Chemical Education, v101 n3 p1356-1360 2024
A structured series of activities has been designed and implemented to promote analysis and data reporting skills for second-year organic chemistry students. Student report sheets were developed to assist students in reporting necessary data for their compounds. A series of rubrics have been utilized by students to promote metacognition and by faculty to promote equitable evaluation. Complete spectral data has been provided for twenty-one student samples; however, the report sheets and rubrics could be used with any unknown organic molecule. In addition to traditional 1D NMR spectra ([superscript 1]H, [superscript 13]C, DEPT-135), 2D NMR spectroscopy data ([superscript 1]H-[superscript 1]H COSY and [superscript 1]H-[superscript 13]C HSQC) has been incorporated into a structure determination laboratory experiment for secon-year organic chemistry students. The experiment described here has been delivered both as both an in-person classroom activity and a remote laboratory experience.
