Geometric Isomerism: The Simplest Illustrator of Orbital Symmetry Control of Molecular Stereochemist maintained along the reaction coordinate while in the latter case a plane of symmetry is preserved during the conversion or reactants to products. This difference with respect to the existing symmetry elements becomes responsible for a difference in the symmetry labels of reactant and product orbit

The Saga of “Hypervalent” Molecules In previous chapters, we have applied this brand of theory to a variety of structural problems with the aim to demonstrate its conceptual and formal advantages over previous and current qualitative theoretical approaches to bonding. We now observe that the Core-Ligand (C-L) dissection allows a clas

Why Benzene prefers to substitute and an Olefin likes to add?e heat of hydrogenation of benzene is much less than the heat of hydrogenation of three cyclohexenes. and the known unwillingness of benzene to undergo addition reactions, opting for “aromatic” substitution instead. These data have prompted an on-going preoccupation with “resonance energies”, “aroma

Why “Effective” Bonds exist when “Real” Bonds are Absent: The Electronic Structure of the (1.1.1.) Ps SCP-MO computations by Newton and Schulman., has no bond linking the bridgehead carbons, but, nonetheless, it is comparatively very stable.. I now show that MOVB theory. easily accounts for these “strange” observations by comparing the electronic structures of the following three molecules.

Textbook 1983he one on which "resonance theory" is based and this fact can be projected by a comparison of the various ways in which MOVB theory depicts a species made up of three core and two ligand MO‘s which define two subsystems containing a total of six electrons and the ways in which "resonance theory" (i.
