SLiThEr #17: Demonstration of a Transition to a Remote General Chemistry Course

Professors Kari Stone and Dan Kissel fro Lewis University describe the transition to a remote general chemistry course through a flipped curriculum using mastery-based grading. In particular, the development and implementation of a element project is discussed as part of the 17th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable) on 3/4/2021

nanoCHAts: Informal conversations about teaching

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

reaction of PPh3 with elements--the COVID edition

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.

The Organometallic Chemistry Behind the Polymer of Squares (Chirik)

The discussion covers a 2021 publication by the Chirik group (Nature Chemistry, 2021, DOI: 10.1038/s41557-020-00614-w) which details the discovery of a new way to polymerize butadiene through iron-catalyzed [2+2] cycloadd

Resolution of Werner complexes -- the COVID edition

This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.

Jahn-Teller effect, theory and examples

At a recent SLiThEr workshop, a request was put out for an introduction to the Jahn-Teller effect. I had already prepared several slides showcasing single crystal X-ray data for my class this spring so I put this together with some additional examples from my lab and the literature.  Single crystal XRD data is presented to support the claims.

ChemCrafter, from the Science History Institute (formerly the Chemical Heritage Foundation), is a free iPad app that mimics a classic chemistry set. It is set up as a game, with three sections: reactions with water, reactions with acid, and salts. The app shows the progress of the reaction (smoke, color change, etc.) when two elements are mixed in a reaction vessel, and also gives the change in enthalpy of the reaction.
