s-p Mixing and the Order of MOs in Diatomic Molecules

These slides provide an introduction to s-p mixing in diatomic molecular orbital diagrams appropriate for students in a general chemistry course.

MO diagram for square planar methane guided inquiry

This guided inquiry activity takes students through the process of constructing an MO diagram for square planar methane. LGOs are constructed using a graphical approach. Students are guided through a process that allows them to use their MO diagram to make a claim about chemical properties.

MO diagram for water guided inquiry

This guided inquiry activity takes the students through the whole process of constructing an MO diagram for water in detail. The LGOs are constructed using my graphical approach (linked below) and hybrid orbital formation is discussed. Along the way, students are given hints on what to think about when constructing an MO diagram.

Inorganic Active Learning Lesson Plan Design

Submitted by Meghan / Indiana University on Fri, 05/15/2020 - 09:05

I created this activity as a way to get the class involved in creating new, fun ways to teach course concepts (selfishly- that part is for me) and for students to review concepts prior to the final exam (for them).  Students use a template to create a 15-20 min activity that can be used in groups during class to teach a concept we have learned during the semester.  We then randomly assign the activities and students work in groups to complete them and provide feedback.

The benefits are twofold:

Ionic Liquids in Action

Submitted by Brad Wile / Ohio Northern University on Thu, 03/05/2020 - 11:46

This was a short LO developed to give the students some context for ionic liquids in use. Since this paper is from a chemical engineering perspective, it supported a goal of having the students think about chemistry outside of the typical inorganic journal/research boundaries. This LO was implemented after a discussion of HSAB/ECW, frustrated Lewis pairs, non-aqueous media, and superacids. No explicit discussion of catalysis prior to this class discussion. 

Applications of Frustrated Lewis Pairs (FLPs)

Submitted by Brad Wile / Ohio Northern University on Thu, 03/05/2020 - 11:22

Short prompts for a mini review about recent applications in FLP chemistry. Trends in Chemistry also includes highlights and outstanding questions in the sidebar, which makes this an approachable review for students.

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.

Triphenylphosphine: Transformations of a Common Ligand

Submitted by Brad Wile / Ohio Northern University on Sun, 06/09/2019 - 11:42

This experiment tasks students with preparing triphenylphosphine sulfide, and the corresponding I2 adduct, then characterizing these products using common instrumental methods. Students are asked to consider MOs and tie this to their Lewis bonding depiction for the final product. This discussion is supported by WebMO calculations and tied to the experimental data obtained by the student.

VIPEr Fellows 2019 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sat, 06/08/2019 - 16:41

During our first fellows workshop, the first 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.
