Point Group Symmetry Game

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 09:59
Description

This is a game that gets students interested in point group symmetry, and helps them to see the symmetry in everyday objects. It is a competition in which the groups try to bring in the hardest object to assign. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

Inorganic Challenge: Lewis structures and VSEPR

Submitted by Patrick Holland / Yale University on Mon, 07/28/2008 - 09:36
Description

This is an Inorganic Challenge that gives students an opportunity to practice the algorithm for difficult Lewis structures, and using good problem-solving technique. Inorganic Challenges are exercises designed to be solved by a small group of students. Some Challenges practice a problem-solving algorithm, some reinforce important concepts, and some involve creativity or games.

Fivefold Bonding in Cr(I) Dimer

Submitted by Maggie Geselbracht / Reed College on Thu, 04/17/2008 - 19:47
Description

This paper describes the synthesis and characterization of a Cr(I) dimer with a very short Cr-Cr distance.  Computational studies support fivefold bonding between the chromium atoms.  I have used this paper to introduce metal-metal multiple bonds and discuss the molecular orbital interactions of homonuclear diatomics including d-orbitals.  More generally, it is a nice example to stimulate the discussion of what constitutes a bond and the various interpretations of bond order.

Miessler and Tarr: Inorganic Chemistry, 3rd. Ed

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Fri, 03/28/2008 - 16:44
Description

Miessler and Tarr is an inorganic textbook which is is best suited to an upper-division one-semester inorganic course, though there is more material than can be covered in a single semester, so some choice of topics is necessary.  It is very well suited for a course oriented around structure, bonding, and reaction chemistry of transition metal compounds, but is very limited in its treatment of solids, main-group, descriptive chemistry, and bioinorganic.  Pchem would be helpful but is not necessary.  In particular, the treatment of MO theory is very in-depth.  The quality of end-of chapter p

Housecroft and Sharpe: Inorganic Chemistry, 3ed

Submitted by Lori Watson / Earlham College on Wed, 03/26/2008 - 20:01
Description

Housecroft and Sharpe (Inorganic Chemistry, 3ed): This is a comprehensive inorganic textbook designed primarily for students at the Junior/Senior level. P-Chem would not be needed as a prerequisite for this text, but would be helpful. It includes both theoretical and descriptive material along with special topics, enough for a two semester course though it is easily adaptable to a one-semester "advanced inorganic" course by choosing only some topics. It is written in a clear and generally readable style and the full-color graphic contribute to student understanding.

Generating LGOs (SALCs)

Submitted by Adam Johnson / Harvey Mudd College on Fri, 01/04/2008 - 19:12
Description

    After several days of lecturing on the topic of polyatomic molecular orbital diagrams, students break into small groups of 3-4 and form LGO’s that can be used to interact with a central atom to form a Molecular Orbital (MO) diagram.  This assignment is part of a larger 4-5 week unit on MO theory. 

Point groups and character tables

Submitted by Joanne Stewart / Hope College on Sun, 11/18/2007 - 14:27
Description

Students practice assignment of symmetry elements and point groups, practice developing a character table, and learn about the link between orbitals and irreducible representations.

Lewis structures and formal charges

Submitted by Joanne Stewart / Hope College on Sun, 11/18/2007 - 14:17
Description

This is a worksheet on Lewis structures and formal charges. The learning goal is for students to be able to use formal charges to defend the relative stabilities of resonance structures of molecules.

Symmetry Scavenger Hunt

Submitted by Lori Watson / Earlham College on Sat, 11/17/2007 - 18:35
Description

Students are sent to find (and take pictures) of  items in various point groups around campus.  Generally, I give them a list of possible offices (though they are free to go to other places) and point groups (some hard) and the following ground rules:
