Computational Analysis of Stereospecificity in the Cope Rearrangement Laura Glish and Timothy W. Hanks
Experimental product distributions from the Cope rearrangement of disubstituted 1,5-hexadienes can be readily understood by computer modeling of the various possible transitions states. Visual analysis of these geometries allow students to interpret the computational results by analogy to the familiar chair and boat conformations of substituted cyclohexanes.

The Mechanism of Covalent Bonding: Analysis within the Hückel Model of Electronic Structure Sture Nordholm, Andreas Bäck, and George B. Bacskay
Hckel molecular orbital theory is shown to be uniquely useful in understanding and interpreting the mechanism of covalent bonding. Using the Hckel model it can be demonstrated that the dynamical character of the molecular orbitals is related simultaneously to the covalent bonding mechanism and to the degree of delocalization of the electron dynamics.

On the Role of d Orbital Hybridization in the Chemistry Curriculum John Morrison Galbraith
The use of d-orbital hybridization to describe hypervalent molecules should be removed from the general chemistry curriculum. The case of bonding in sulfur hexaflouride can illustrate that no theory provides all the right answers all the time.

Why the Lower-Energy Term of Singlet Dioxygen Has a Doubly Occupied π* Orbital Terry S. Carlton
The singlet term of dioxygen with one doubly occupied p* orbital has lower energy than the singlet term with two singly occupied p* orbitals even though single occupancy is favored in the aufbau of atoms. A simple physical explanation based on orbital angular momentum explains this double occupancy.

Moving Beyond the Single Center—Ways To Reinforce Molecular Orbital Theory in an Inorganic Course Marion E. Cass and William E. Hollingsworth
Rather than ending the discussion of molecular orbital (MO) theory in an inorganic chemistry course with molecules such as octahedral ML6 or square planar ML4, we suggest moving beyond the single-atom center to include the MO diagram of ethene (C2H4).

A Unified Approach to Electron Counting in Main-Group Clusters John E. McGrady
A unified approach to electron counting in main-group cluster chemistry is presented, wherein the different classes, electron-rich, electron-precise, and electron-deficient, are viewed simply as different regions of a continuum defined by two variables, vertex count and valence electron count.

Organizing Organic Reactions: The Importance of Antibonding Orbitals David E. Lewis
It is proposed that unoccupied molecular orbitals arbitrate much organic reactivity, and that they provide the basis for a reactivity-based system for organizing organic reactions. Such a system is proposed for organizing organic reactions according to principles of reactivity, and the system is discussed with examples of the frontier orbitals involved.

A Simple Qualitative Molecular-Orbital/Valence-Bond Description of the Bonding in Main Group "Hypervalent" Molecules Owen J. Curnow
A multicenter valence-bond/molecular-orbital bonding scheme for main group "hypervalent" molecules is proposed which extends the 3-center-4-electron (3c-4e) bonding model of Rundle and Pimentel to include 4c-6e, 5c-8e, and 6c-10e bonds. This model allows the determination of bond orders and a rationalisation of bond distances.

Models to illustrate orbital symmetry effects in organic reactions Brown, Peter
From a pedagogic point of view, conservation of orbital symmetry is easily assimilated by students with a rudimentary knowledge of simple MO theory and of symmetry. The author has found in teaching over the past three years at both graduate and undergraduate levels that use of a simple set of orbital models as described in this article has enormous advantages as a visual aid in the construction and assignment of symmetry elements to the appropriate semi-localized Huckel-type MOs and in following their stereo chemical fate in concerned reactions.
