The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.
This literature discussion focuses on a paper from the Angelici lab that examines the heat of protonation of [CpʹIr(PR3)(CO)] compounds. The compounds presented in the paper provide good introductory examples for electron counting in organometallic compounds. The single carbonyl ligand in these compounds provide an excellent probe to monitor the electron richness at the metal center which is impacted by the electron donor ability of the ligands.
Equilibrium reactions are those that are dynamic: the reaction can shift to form more reactants or more products depending on the physical or chemical conditions present. They were discovered and described empirically, but have a thermodynamic basis in the Gibbs Energy of the reaction. A reaction at equilibrium has both reactants and products present, and the rate of formation of products is equal to the rate of formation of reactants. A common application of equilibrium is the chemistry of aqueous acids. Acid strength is measured by the pH scale.

At this website, you will find a link to the syllabus and all lecture videos for a "flipped" version of an Advanced Inorganic Chemistry Course taught at Saint Mary's College (Notre Dame, IN). I used Shiver & Atkins for this course, and the format is based off of Dr. Franz's course at Duke. If anyone is interested in the problem sets, I will be happy to share, although much of the material I used is from VIPEr.
This is the procedure for a Fe(III) catalyzed synthesis of aspirin, an alternative to the traditionally sulfuric acid catalyzed synthesis of aspirin. The prep compares and contrasts the Bronsted acid catalyzed esterification reaction with a Lewis acid iron (III) catalyzed pathway. This can be used in different courses at different levels, but is it written for a general/intro level chemistry course.
Frustrated by the lack of inorganic textbooks that really fit my materials-oriented first-semester inorganic course, I embarked on a project with my students to create a free online textbook. The students did most of the heavy lifting, and I'm pleased to report that the next class to use the book rather liked it. It is still a work in progress, but I would like to encourage everyone to check it out and edit it if the spirit moves you.
The slides provide review questions for a senior-level treatment of the spectroscopy and reactivity of metal carbonyl complexes. These are intended to be dispersed through one to three class periods.
The first slide is a review of electron counting and the 18-electron rule.
The second slide quizzes the students on the relationship between the electron-density of the metal center and the strength of the C-O bonds in the carbonyl ligands. It is intended to be given after a discussion of how IR can be used to assess the strength of M-C and C-O bonds in the compounds.
