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:
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.
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.
For many years I have resisted using clickers, mainly because at our university there is no standard universal clicker. I wanted to keep student costs as low as possible but also desired the type of live feedback during a lecture that clicker questions can provide. In both my general chem. (200-300 students) and upper division courses (50-75 students), I now pass out 4 or 5 colored notecards on the first day of class and make sure everyone has one of each color.
This is a powerpoint quiz show review that can be used to help students assess themselves on their level of understanding of simple bonding theory and some simple molecular orbital theory. It is appropriate for use in a general chemistry course or at the beginning of an advanced inorganic chemistry course to review simple bonding theory. It was developed as an alternative to using clickers for those departments that do not have clickers or would prefer not to set up clicker questions. Correct answers are shown at the end of each slide.
This learning object is a literature discussion based on a paper published in Nature (Labinger, J. A.; Bercaw, J. E. Nature 2002, 417, 507-514; doi:
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.
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.
This is an addendum to the Manganese Carbonyl experiment (linked below). In this part of the experiment, students carry out high level quantum mechanical calculations of reactants, intermediates, and products in order to determine which of two possible structures is correct.
In Haverford College's course Chem 111:Structure and Bonding, we have included a workshop exercise that guides students through their first experience using electronic structure calculations. We use the WebMO interface along with Gaussian03, but the exercise could be adapted for other electronic structure programs. The general structure of the exercise is as follows:
