Writing assignment series related to topics discussed in organometallic chemistry - Assignment 1 Literature Summary

Submitted by Abby O'Connor / The College of New Jersey on Mon, 07/16/2012 - 10:58
Description

Searching and reading the literature is an important tool in teaching organometallic chemistry. This overall project focuses on the improving students' writing skills and to begin to think critically about articles in the literature through a series of different writing assignments. This project is used in a semester long course on organometallics and reaction mechanisms. The first assignment (this LO) is a summary, the second is related to the NSF highlight, and the third is a literature critique.

Synthesis and Characterization of Ferrocene, Acetylferrocene and Ferrocenylethanol

Submitted by Henry Acquaye / Department of Chemistry, University of Redlands on Mon, 07/16/2012 - 10:57
Description

This project is designed to develop the research skills that are required to tackle projects that are larger and more complex than those encountered in first and second year chemistry courses.  The lab is an integrated project-oriented laboratory including synthesis and the use of instrumental techniques such as UV-Visible and infrared, 1H-NMR and 13C-NMR spectrometry, chromatography (HPLC, TLC) and cyclic voltammetry.

Solubility and the Need for Bioinorganic Metal Ion Transport and Storage

Submitted by Sheila Smith / University of Michigan- Dearborn on Mon, 07/16/2012 - 09:42
Description

 

This is an in class exercise that I use to emphasize the need for metal ion transport and storage in biochemistry.  Applying the Van't Hoff equation to the Ksp value at 25°C for ferric hydroxide, students calculate the iron concentration at which ferric hydroxide would begin to precipitate out in the blood.  It' s an interesting problem that requires very little math beyond that used in gen chem, and the answer is in stark contrast to the amount of iron that we actually store in our bodies.  

High Energy Density Materials: A laboratory and literature investigation (Christe)

Submitted by Kevin Hoke / Berry College on Fri, 07/13/2012 - 21:12
Description

The synthesis of the nitrogen triiodide ammoniate shock-sensitive explosive is a simple laboratory exercise, but it does require a lengthy time for the material to dry before it is active.  This activity uses that time to have students investigate some simple thermodynamics behind their explosive, as well as consult the literature on high energy density materials from the work of Karl O. Christe.

There is also a shorter version of the activity posted as an in-class activity that omits most of the literature investigation.

Modeling the FeB center in Bacterial Nitric Oxide Reductase: A Reading Guide

Submitted by Sheila Smith / University of Michigan- Dearborn on Fri, 02/24/2012 - 11:52
Description

In 2011, I was fortunate to have Nicolai Lehnert come and speak to my bioinorganic class on his work modeling the FeB (non heme iron) center in bacterial Nitric Oxide reductase.  He suggested this paper to prepare the students for his talk and I developed this reading guide to help them (the students) get more out of the reading.

CBC (Covalent Bond Classification) Method of Electron Counting

Submitted by Chip Nataro / Lafayette College on Thu, 02/02/2012 - 12:29
Description

This series of slides works through an example of electron counting using the CBC (Covalent Bond Classification) method. It compares and contrasts the classic ionic and covalent methods to the CBC method. The example used in these slides is an exception to the 18 electron rule using the the classic methods, but by CBC classification it is a very common ML4X4 tetravalent 16 electron Ti compound.

Inorganic Nomenclature and Point Group Identification: Combined In Class exercise

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 01/26/2012 - 09:44
Description

I use this exercise in my 400-level Inorganic (Transition Metals) course.  Students have been introduced to assigning point groups in a 300- level Inorganic course on bonding theories.  Therefore, I combine a review of assigning point groups with the introduction to inorganic nomenclature in my advanced course.  This seems to break up the tedium of the rules for nomenclature while stressing that the need for such elaborate names comes from the need to correctly identify one structure among may isomeric possibilities.

Energy Nugget: Methane to Methanol

Submitted by Hilary Eppley / DePauw University on Thu, 01/12/2012 - 05:40
Description

This learning object was developed with a lot of help from B. Scott Williams from the Keck Science Department of the Claremont Colleges for my junior/senior level course in 2009.   This object is a literature discussion on the topic, but Scott and I hope to add a 5-slides about learning object to go with it shortly.   The primary literature article used for the discussion is “Characterization of a Rhodium(I) sigma-Methane Complex in Solution,” by Wesley H. Bernskoetter, Cynthia K. Schauer, Karen I.

Comprehensive Character Tables and Reducible Representation Tool

Submitted by Austin Scharf / Oxford College of Emory University on Wed, 01/11/2012 - 11:05
Description

This site is an excellent, well-organized collection of the chemically relevant character tables.  I find it particularly helpful because it includes the cubic functions, allowing you to determine the symmetry labels of the f orbitals in a given point group; these are not included in most of the collections of character tables in general inorganic chemistry textbooks.  Additionally, it has a tool that automatically reduces (correctly derived) reducible representations into their component irreducible representations.

Exploding the Myth of Intracellular free metal ion pools_ A reading guide

Submitted by Sheila Smith / University of Michigan- Dearborn on Thu, 09/22/2011 - 15:18
Description

This is a Reading guide to the Review article Transition Metal Speciation in the Cell: Insights from the Chemistry of Metal Ion Receptors Lydia A. Finney, et al. Science 300, 931 (2003);
