5.111 Principles of Chemical Science
5.111 Principles of Chemical Science (Fall 2014, MIT OCW). Instructor: Professor Catherine Drennan. This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. One year of high school chemistry is the expected background for this freshman-level course.
Lecture 12 - The Shapes of Molecules: VSEPR Theory. Valence shell electron pair repulsion or VSEPR theory can be used to predict molecular geometry. The theory is based on Lewis structures and the simple idea that that the preferred geometry around a central atom is the one that minimizes electron repulsion. Chemist Stefanie Sydlik tells us how she uses VSEPR theory to design sensors that are capable of detecting landmines.
