This experiment explores isotopic substitution as a method to identify stretching frequencies and linking experimentally determined parameters with theoretical predictions utilizing a simple harmonic oscillator obeying Hooke’s law.
In this in-class activity, students will determine the formal oxidation state of transition metal complexes by performing bonding type analysis of ligand−metal bonds. This in-class project is intended for those with little background in inorganic chemistry and aims to provide simple methods to calculate the formal charge of transition metals through bond-type analysis. While there are more sophisticated models already available to assign transition metal oxidation states, such as the LXZ (CBC) model, this exercise is intended for students who are coordination chemistry novices.
This learning object is aimed at getting students to think critically about the data they collect in lab as they collect the data similar to how chemists typically conduct research. They will be given a pre-lab video and a procedure prior to lab, conduct the experiment, and then upload their data to an Excel spreadsheet. Students will then stay in their group to discuss the questions given to them on the worksheet in class with the instructor, and are allowed to continue working on them as a group up until the due date.
This assignment is intended to help students develop basic literature reading comprehension skills as well as connect the course content to relevant primary literature. Additionally the activity is coupled to short presentations that develop communication skills.
In the humanities it is common practice to read a piece of literature and discuss it. This is also practiced in science and is the purpose of this exercise. Each student is assigned a communication from the current literature (inorganic, JACS, organometallics, J. Phys.
This is a worksheet for students to complete in class to practice nomenclature of coordination compounds. It may alternatively be assigned as homework after a lesson on nomenclature. Includes examples of Ewing-Bassett system as well as Stock system.
Students are asked to choose a type of reaction from a set list (included), determine appropriate starting materials and the resulting product and present the reaction as though they accomplished it in the laboratory setting (5 min oral presentation with a 1 page paper). I asked the students to perform both a rough draft presentation (to me) and final draft presentation (to all students in laboratory).
This worksheet was designed to give students an introduction to organic chemistry nomenclature with a more active experience than listening to a faculty member present all the rules for how to name alkanes and cycloalkanes. The pedagogical approach is one introduced to me by Dr. Melonie Teichert; we refer to it as ICC (Inventing through Contrasting Cases). The theoretical framework involves the premise that students will learn and retain more of the learning if they're not simply told the "answer" but if they attempt to generate an answer for themselves based upon a data set.
We do not cover extended solids (solid state materials) in our general chemistry program. With the exception of students who have taken a course in materials science, Inorganic Chemistry I is the first time our students have encountered solid state structure. Although they have built some visualization skills by working with molecules and symmetry, they do not have robust 3D visualization abilities and have trouble using the language of solid state chemistry (unit cells, packing, filling holes, coordination number, etc…) in the context of structure.

this chapter covers halides, oxygen and nitrogen donor ligands
The powerpoint slides contain answers to some of the in-class exercises, so those are behind the "faculty only" wall. I share these with students after the class, but not before.
Everyone is more than welcome to edit the materials to suit their own uses, and I would appreciate being notified of any mistakes that are found.
