Popular problem sets

Submitted by Chip Nataro, Lafayette College

In January I wrote about the most adopted/favorited Lit. Discussion LOs and at that time I promised to make this a somewhat regular series on BITeS. Not wanting to disappoint my vast audience, I thought it was time for the second in the series, this time taking a look at the most adopted/favorited Problem Sets. Once again, there are some ties, so the numbering might look a little odd, but trust me, there will be 10. Just a reminder, this list comes from you, the loyal VIPEr users. You have the power to change this list in the future. If you aren't quite sure how to do this, every LO has a section entitled My Notes just beneath the Title and author list. There you can mark the LO as being adopted or a favorite (or even both).

7. In a 4-way tie we have...

Atomic Orbital Comparison by Anne Bentley - In this exam question, students are asked to compare the radial probability functions of an orbital in different atoms.

Ni(II) Ni(III) Ni(IV) Electron Counting and Geometries by George Lisensky, et al. - From our 2016 workshop at the University of Michigan, this LO has students looking at electron counts and geometries for a series of tris(pyrazoyl)borate nickel compounds from the lab of Melanie Sanford.

Fundametal Quizzes: Atomic Orbitals by Barb Reisner - While Barb herself says this isn't quite a problem set, it is easily adaptable into one. Barb uses these questions as an early semester quiz to probe what her inorganic students have retained from general chemistry.

Inorganic Chemistry Pretest by Hilary Eppley - Similar in concept to the previous LO but broader in scope, Hilary gives a surprise quiz to her inorganic students on the first day of class.

5. Our last tie on the list

Chaging Quantum Numbers (make your own universe) by Barb Reisner - Our only repeat author on this list, Barb challenges students to see how well they get quantum numbers.

IR and Raman Spectrosopy of Cobalt Boronyl Tetracarbonyl, Co(BO)(CO)4 by Maggie Geselbracht -  I'm not going to lie, this is my personal favorite on the list. It is a great application of group theory for looking at the vibrational spectroscopy of this cobalt compound.

4. Crystal Field, Sigma/Pi Properties, and Color by Nancy Williams - Your lab partner is a hot mess and you have to clean up after them. This LO has students determine the relationship between d-orbital splitting and color.

3. Zinc Finger Proteins: A Bioinorganic Example of LFSE and HSAB by Betsy Jamieson - This LO uses a seemingly complex bioinorganic example to show off the fundamental inorganic topics of LFSE and HSAB.

2. Trends in Z* of 4s and 3d orbitals in first row transition metals by Karen McFarlane Holman -  An application of Slater's Rules to look at why orbitals fill in the order they do.

And the most adopted/favorited Problem Set LO is...

1. Rubredoxin and the Jahn-Teller Effect by Christopher Bailey - Students examine a tetrahedral iron complex and figure out the relationship between number of d electrons in the compound and Jahn-Teller distortion.



Wow. Just saw this list. I am looking forward to using some of these on our first exam and throughout the rest of the semester.
