A systematic study of both the fundamental principles and the descriptive chemistry needed to understand the properties of the main group elements and their compounds. (Three lecture, one recitation, and three laboratory hours per week) Prerequisites: CHEM 1200.
Our CHEM145 is offered once every two years: TR 75 min synchronous lectures, F 4 h in-person lab.
This literature discussion shows how serious inorganic chemistry topics can related to cultural heritage problems. The paper is pretty dense in EPR and UV/Vis spectroscopy, but the questions don't go in super great depth on those topics instead focusing on the problem, the main findings, structures and the experiment design, with some additional questions about the spectroscopy.
This course will emphasize the fundamental concepts needed to understand the diverse chemistry of all the elements of the periodic table. The common theme for the entire course will be Structure and Bonding. The primary focus will be inorganic molecules, ions and solids, but the concepts we will discuss are applicable to all aspects of chemistry. The first two-thirds of the course will cover theories of bonding in molecules and solids along with some background in symmetry and structure.
A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.
This literature discussion highlights recent research from the Rosenzweig group that probes the structural and spectroscopic properties of a newly discovered, atypical CuA site located in a PmoD protein in a new class of methane-oxidizing bacteria.
This is a research-like laboratory experience based on the one posted by Brad Wile (linked below). My students are mostly juniors and have had 2 semesters of organic. This spring they are taking the inorganic laboratory virtually, so I wanted to give them a more exploratory lab experience. Their job will be to watch the YouTube videos to see the synthesis and isolated products, and then propose characterization methods they want to employ to identify both the identity and purity of the compounds.
This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.
For our virtual offering of inorganic chemistry laboratory at Harvey Mudd College in Spring 2021, I made some videos and collected some high quality data (IR, 1H NMR, MS, UV-Vis, mp, and X-ray diffraction) that I will make available for my students. The videos show the synthesis of Co and Mn acacs, the difference between as-prepared and recrystallized compounds, making solutions for UV-Vis and Evans method NMR, and making Evans method capillary tubes. The procedures for the synthesis of these compounds is found in Woolins (either the first or second editions).
In this literature discussion, students are asked to explore the chemistry behind a eta-1 to eta-2 linkage photoisomer of sulfur dioxide bound to pentammine osmium. There are questions that tie to chemical structure and the nature of the two bonding modes of the ligand as well as an examination of the spectroscopic properties of the complex in the solid state. Two of the questions ask students to draw some conclusions based on their knowledge of periodic trends and the sigma donor ability of ligands.
