Reversible, Metal-Free Hydrogen Activation (Stephan)

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

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
Description

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 / St. Lawrence University on Mon, 02/21/2022 - 11:08
Description

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
Description

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.

Inorganic Chemistry

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

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
Description

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.

Descriptive Inorganic Chemistry

Submitted by Kim Woznack / PennWest-California on Fri, 01/14/2022 - 12:48
Description

This course focuses on the concepts of inorganic chemistry with emphasis on atomic structure, periodicity, group and bonding theories, symmetry, solid-state structures of metals, ionic compounds and semiconductors, as well as transition metal coordination chemistry.   

Analysis of an Inorganic Chemistry Literature Article

Submitted by Catherine McCusker / East Tennessee State University on Wed, 01/05/2022 - 14:17
Description

In this assignment students search for and choose an inorganic chemistry related research article. After reading, students write an analysis of their article, explaining the background, experimental data, and conclusions to their classmates.
