Redox-switch polymerization catalysis

Submitted by Chip Nataro / Lafayette College on Tue, 03/26/2019 - 13:49
Description

This is the full literature discussion based on a communicaiton (J. Am. Chem. Soc. 2011, 133, 9278). This paper describes a redox-switch yttrium catalyst that is an active catalyst for the polymerization of L-lactide in the reduced form and inactive in the oxidized form. The catalyst contains a ferrocene-based ligand that serves as the redox active site in the catalyst. This full literature discussion is an extension of the one figure literature discussion that is listed below.

1FLO: Redox-switch polymerization catalysis

Submitted by Chip Nataro / Lafayette College on Fri, 03/22/2019 - 16:11
Description

This is what I hope will be a new classification of learning object called a one figure learning object (1FLO). The purpose is to take a single figure from a paper and present students with a series of questions related to interpreting the figure. This literature discussion is based on a paper (J. Am. Chem. Soc. 2011, 133, 9278) from Paula Diaconescu's lab in which a yttrium polymerization catalyst with a ferrocene-based ligand can effectively be rendered active or inactive depeneding on the valence state of the ligand.

5-ish Slides About Bridging Hydrides and the [Cr(CO)5HCr(CO)5] anion

Submitted by Kyle Grice / DePaul University on Thu, 01/31/2019 - 13:52
Description

This set of slides was made for my Organometallics class based on questions about bridging hydrides and specifically the chromium molecule. I decided to make these slides to answer the questions, and do a DFT calc to show the MO's involved in bonding of the hydride. 

 

Inorganic Chemistry

Submitted by James F. Dunne / Central College on Tue, 01/29/2019 - 16:16
Description

This course is an introduction to the field of inorganic chemistry.  The student is expected to be well-versed in the material covered in general chemistry, as this will serve as the foundation and launching point for the material to be covered this semester. The course will begin by examining the properties of the elements, and expand outward to consider chemical bonding and the electronic factors that govern metal reactivity.  These factors include acid-base theory, thermodynamics, electrochemistry and redox, and coordination chemistry.

Inorganic Chemistry

Submitted by Kari Young / Centre College on Mon, 01/28/2019 - 11:23
Description

A study of the chemistry of inorganic compounds, including the principles of covalent and ionic bonding, symmetry, periodic properties, metallic bonding, acid-base theories, coordination chemistry, inorganic reaction mechanisms, and selected topics in descriptive inorganic chemistry. Laboratory work is required.

Special Topics in Inorganic Chemistry - Inorganic Photochemistry

Submitted by Catherine McCusker / East Tennessee State University on Wed, 01/16/2019 - 17:21
Description

The class is divided into two parts. In the first part students learn the physical principles involved with the absorption of light and the photophysical and photochemical processes that may occur aafter the abosrption of light. The second part uses literature discussions and student presentations to explore applications of photophysical and photochemical reactions in inorganic chemistry 

Descriptive Inorganic Chemistry

Submitted by Catherine McCusker / East Tennessee State University on Wed, 01/16/2019 - 16:26
Description

This course is designed to give an introduction to the concepts of electronic structure, bonding,

and reactivity in inorganic chemistry. The field is too vast to comprehensively cover every aspect in

a single semester, so this class will offer a qualitative overview of inorganic chemistry. Reading and

understanding scientific literature is an important skill for any scientist to have, whether you move

on to grad school, professional school, or the job market, so relevant literature articles will be

Quantum Numbers and Nodes: A General Chemistry Flipped Classroom Module

Submitted by Jack Eichler / University of California, Riverside on Sat, 11/17/2018 - 11:27
Description

This is a flipped classroom module that covers the concepts of quantum numbers, and radial and angular nodes. This activity is designed to be done at the beginning of the typical first quarter/first semester general chemistry course (for an atoms first approach; if instructors use a traditional course structure this unit is likely done towards the middle/end of the first quarter/semester). Students will be expected to have learned the following concepts prior to completing this activity:

a) quantization of energy in the atom and the Bohr model of the atom;
