So Much Nitrogen: Maggie's Explosive Main Group Compounds

Submitted by W. Stephen McNeil / University of British Columbia Okanagan on Thu, 03/21/2013 - 00:47

Maggie Geselbracht has a great fondness for compounds with too many nitrogen atoms next to each other.  This is a collection of problem sets and class activites based on the structure, bonding, and spectroscopy of a number of such compounds, drawn from the recent literature.

Metal-Ligand Multiple Bonds and Frustrated Lewis Pairs

Submitted by Matt Whited / Carleton College on Wed, 10/10/2012 - 14:40
Description

This is a literature-based activity that focuses on a review I recently published as part of a thematic series on C-H activation.

The review highlights similarities between the newly discovered frustrated Lewis pairs and polarized metal-ligand multiple bonds.  There are many ways to use the review, but the attached set of questions focuses on drawing analogies among seemingly diverse types of reactivity using frontier-molecular-orbital considerations.

Atomic Orbital Display

Submitted by Flick Coleman / Wellesley College on Thu, 10/04/2012 - 12:26
Description

This is a jmol display of the atomic orbitals from 1s to 4f that can be rotated in space. They are plotted relative to the x, y, and z-axes.

The Lewis Dot Structure(s) of Nitryl Fluoride

Submitted by Sheila Smith / University of Michigan- Dearborn on Wed, 09/26/2012 - 20:43
Description

This is the In Class Activity that I use to review the concepts of Lewis Dot Structures, LDS, (connectivity, resonance, formal charges, etc.) learned in General Chemistry and to introduce new ideas of resonance contributions to the character of the molecule.  The question itself is apparently very simple, but the discussion that it produces can be quite rich and brings in both new and old ideas of LDS, providing both a good review and a good segue into advanced ideas of Lewis Dot Structures.

Exploration of Nitrosyl Complexes

Submitted by Brad Kraft / St. John Fisher College on Mon, 07/30/2012 - 15:33
Description

This in-class activity and the related problem set allows students to discover the linear and bent bonding modes of NO to metals based on VSEPR theory through guided inquiry.  Two examples follow which illustrate how the electrons are counted in NO complexes depending on the coordination mode/formal charge of NO. Students must have had prior practice in counting electrons of complexes to complete the problems.   

Soluble Methane Monooxgenase Spectroscopy

Submitted by Gerard Rowe / University of South Carolina Aiken on Fri, 07/20/2012 - 09:37
Description

Determining the reactive intermediates in metalloenzymes is a very involved task, and requires drawing from many different spectroscopies and physical methods.  The facile activation and oxidation of methane to produce methanol is one of the "holy grails" of inorganic chemistry.  Strategies exist within materials science and organometallic chemistry to activate methane, but using the enzyme methane monooxygenase, nature is able to carry out this difficult reaction at ambient temperatures and pressures (and in water, too!).

Exploring the Nanoworld Innovating through Materials from the University of Wisconsin Madison

Submitted by Patricia Stan / Taylor University on Thu, 07/19/2012 - 13:29
Description

This is a great web resource for all types of nano materials.  There are lesson plans, demos, activites, labs and lots of background information.  It is very easy to navigate and there are videos of the labs so you can see each step - very useful when doing a type of synthesis or technique new to you.

ChemTube3D

Submitted by Anthony L. Fernandez / Merrimack College on Thu, 07/19/2012 - 08:51
Description

ChemTube3D is a website maintained by the University of Liverpool that has interactive 3D animations ans structures.  The content is broken up into several areas:

  • A Level;
  • Organic Reactions;
  • Structure and Bonding;
  • Polymers;
  • Solid State.

There is a lot of information on the site, and the information could be used in many courses.  The areas that I find most useful in my sophomore-level inorganic chemistry course.

C(sp3)-F Activation through an Initial C(sp3)-H Activation Mechanism

Submitted by John Lee / University of Tennessee Chattanooga on Wed, 07/18/2012 - 16:35
Description

This paper is from a Science article from Alan Goldman’s group at Rutgers University. It was one of the literature articles that was assigned during the IONiC VIPEr Workshop in July 2012.  In conjunction with reading the article, workshop participants attended a seminar presented by Alan Goldman on this work.
