A New "Bottom-Up" Framework for Teaching Chemical Bonding Tami Levy Nahum, Rachel Mamlok-Naaman, Avi Hofstein, and Leeor Kronik This article presents a general framework for bonding that can be presented at different levels of sophistication depending on the student's level and needs. The pedagogical strategy for teaching this model is a "bottom-up" one, starting with basic principles and ending with specific properties. Levy Nahum, Tami; Mamlok-Naaman, Rachel; Hofstein, Avi; Kronik, Leeor. J. Chem. Educ. 2008, 85, 1680.

Six Pillars of Organic Chemistry Joseph J. Mullins This article focuses on a core set of conceptselectronegativity, polar covalent bonding, inductive and steric effects, resonance, and aromaticitythe proper application of which can explain and predict a wide variety of chemical, physical, and biological properties of molecules and conceptually unite important features of general, organic, and biochemistry.

Chemical Bonding as a Superposition Phenomenon Frank Weinhold The characteristic phenomena of chemistry-covalent and coordinate bonding, resonance delocalization, aromaticity, H-bonding, hyperconjugation-can also be seen as special cases of a central superposition paradigm: the "donor-acceptor" interaction between filled and unfilled orbitals.

The Use of Molecular Modeling and VSEPR Theory in the Undergraduate Curriculum to Predict the Three-Dimensional Structure of Molecules Brian W. Pfennig and Richard L. Frock Despite the simplicity and elegance of the VSEPR model, however, students often have difficulty visualizing the three-dimensional shapes of molecules and learning the more subtle features of the model, such as the bond length and bond angle deviations from ideal geometry that accompany the presence of lone pair or multiple bond domains or that result from differences in the electronegativity of the bonded atoms, partial charges and molecular dipole moments, and site preferences in the trigonal bipyramidal electron geometry. Pfennig, Brian W.; Frock, Richard L. J. Chem. Educ. 1999, 76, 1018.

Teaching Chemistry with Electron Density Models Gwendolyn P. Shusterman and Alan J. Shusterman This article describes a powerful new method for teaching students about electronic structure and its relevance to chemical phenomena. This method, developed and used for several years in general chemistry and organic chemistry courses, relies on computer-generated three-dimensional models of electron density distributions. Shusterman, Gwendolyn P.; Shusterman, Alan J. J. Chem. Educ. 1997, 74, 771.

Principles of electronegativity Part I. General nature Sanderson, R. T. The concept of electronegativity has been modified, expanded, and debated. The concept can be used to help students gain valuable insights and understanding of the cause-and-effect relationship between atomic structure and compound properties. This is the first in a series of articles that explores the important concept of electronegativity. Sanderson, R. T. J. Chem. Educ. 1988, 65, 112.
