Introduction to Borane and Carborane Clusters: Practice with Point Groups, Electron Counting, and Electronegativity with Computational Support

This LO uses borane and carborane clusters to practice assigning point groups and counting electrons. It also asks students to recall electronegativity trends to predict dipoles, and they can check their predictions against calculated Mulliken charges.

1FLO: Perhalogenated Carba-closo-dodecaborate Anions as Ligand Substituents: Applications in Gold Catalysis

Submitted by Megan Mohadjer Beromi / United States Naval Academy on Mon, 06/27/2022 - 19:58

This 1FLO focuses on the fundamentals of catalysis and the interpretation of catalytic data. The questions guide students through the definition of catalysts, turnover frequency, turnover number, and require the students to extract information from a table of catalytic data. The data set comes from the unprecedented activity of carba-closo-dodecaborate ligated gold catalysts in hydroamination reported by Lavallo and coworkers in 2013 (Lavallo, V.; Wright II, J. H.; Tham, F. S.; Quinlivan, S. Angew. Chem. Int. Ed. 2013, 52, 3172.

VIPEr Fellows 2022 Workshop Favorites

The second cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

Reversible, Metal-Free Hydrogen Activation (Stephan)

Submitted by Todsapon T. / University of Evansville on Tue, 03/01/2022 - 16:35

This LO discuss various aspects of a reversible hydrogen activation by a metal-free phosphonium-borate compound.  Attentions are paid to the specific and usual reaction between highly steric phosphine and borane reactants to form a zwitterionic phosphonium borate product.  NMR spectroscopy, kinetics and thermodynamics of the hydrogen activation with the phosphonium borate product are also discussed.  The original work was published in Science by Douglas W. Stephan and co-workers.

VIPEr nanoCHAt : NeWBiEs Spring 2022 Learning Objects

Submitted by Shirley Lin / United States Naval Academy on Wed, 02/02/2022 - 18:07

This collection accompanies the IONiC VIPEr nanoCHAt video series NeWBiEs, recorded in Spring 2022. This series is comprised of weekly conversations with two IONiC members, Wes Farrell and Shirley Lin from the US Naval Academy, as they taught a foundation-level inorganic chemistry course for the first time. The LOs discussed in the videos are included in this collection.

The N5+ Cation: Explosive Chemistry and Raman Analysis (Christe) - Expanded and Updated

Submitted by Katheryn Cruz / University of Texas at Arlington on Tue, 08/03/2021 - 12:32

This paper discusses the synthesis and characterization of a novel compound of nitrogen.  The pre-discussion assignment asks students draw a Lewis structure for the N5+ cation, and using the tools of group theory, conduct a normal mode vibrational analysis, comparing the results to the experimental Raman spectral data.­­
