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.

Structures of Solids - Unit Cells, Close-Packing, and Ionic Materials

Submitted by Dean Johnston / Otterbein University on Mon, 02/28/2022 - 16:16

This website displays interactive models of the unit cell contents of simple cubic, body-centered cubic, face-centered cubic, and hexagonal close-packed structures, in addition to several simple ionic compounds. Relationships between the close-packed atomic layers, the unit cell contents, and the structures of related ionic materials are highlighted.

Review of Atomic Orbitals and Guided Tour of the Orbitron

Submitted by Patrick Lutz / Oberlin College on Mon, 02/21/2022 - 11:08

This activity was created to extend the "First Day Review of Atomic Orbitals" LO to take up a full class period. The first part of the activity is likely familiar to many VIPER users, asking students to brainstorm and review key concepts related to atomic orbitals. (The author participated in this very activity as a student circa 2010!) The second part of this LO is new and leads students on a guided tour of the Orbitron website to review or discover the shapes of atomic orbitals and their nodal properties.

Free Energy of Activation & Reaction Completion Times

Submitted by Joanna Webb / West Virginia Wesleyan College on Thu, 02/17/2022 - 13:39

This spreadsheet uses the Eyring equation to draw a connection between activation barriers and the timescale of a reaction. Students input a free energy of activation and can quickly see how long a reaction will take at varying temperatures. This has been particularly useful in computational sections of literature articles that investigate possible mechanistic pathways.

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.

Inorganic Chemistry

Submitted by Jason Smee / University of Texas at Tyler on Wed, 01/19/2022 - 16:07

Introductory topics in inorganic chemistry including descriptive inorganic chemistry, solid-state chemistry, and coordination chemistry with the latter area consisting of nomenclature, stereochemistry, bonding, and reaction mechanisms. 

Essential Inorganic Chemistry

Submitted by David Benson / Calvin University on Tue, 01/18/2022 - 19:10

Course Description: This foundational course for 2nd-year students covers the properties and trends of molecules derived from across the periodic table. In addition to main-group elements, a deeper understanding of transition metal ions will be developed. Topics covered include periodicity, bonding, symmetry, and reactivity.

Inorganic Chemistry

Submitted by Laurel Goj Habgood / Rollins College on Mon, 01/10/2022 - 16:45

The course is currently designed for a student population impacted by COVID and College policies that the department offer this course every third semester. This semester I have a diverse student population in terms of developmental levels including cohort year (freshman, junior, senior), prior foundational course work (biochemistry, analytical, physical), and research experience. I have altered the assessment part of the course substantively from prior iterations and reduced topic coverage to provide flexibility.

Inorganic Chemistry 1

Submitted by Stephanie Poland / Rose-Hulman Institute of Technology on Mon, 01/10/2022 - 10:16

Course catalog description: The chemistry of non-metals. This course consists of a systematic study of the properties and reactions of the elements and their compounds based upon modern theories of the chemical bond, as well as from the viewpoint of atomic structure and the periodic law.
