My Notes

This is a research-like laboratory experience based on the one posted by Brad Wile (linked below). My students are mostly juniors and have had 2 semesters of organic. This spring they are taking the inorganic laboratory virtually, so I wanted to give them a more exploratory lab experience. Their job will be to watch the YouTube videos to see the synthesis and isolated products, and then propose characterization methods they want to employ to identify both the identity and purity of the compounds. 

Learning Goals

students will use their chemical knowledge to select the most appropriate characterization for a series of unknown molecules

students will use their characterization data to determine the identity and purity of an unknown 

students will learn to interpret NMR, MS and other data in a more advanced way (NMR satellites, molecular ion envelopes)

Equipment needs

pdf reader and access to YouTube

Implementation Notes

I am implementing this experiment for the first time in March 2021 in our virtual laboratory for inorganic chemistry. All the data available to students does NOT reveal the identity of the products. Some of the data (XRD) does reveal the identity, so that is listed under instructor resources.

Time Required
2-3 3-4 hour lab periods
Evaluation Methods

Students will be evaluated according to the information in the instructor resources. They will write a preliminary report on the two molecules for their group, give a short presentation, and then write a final report on all molecules.

Evaluation Results

will be added later
