Bonding : ImpossibleStructure (10 Variations)
Which of the following formulas represent substances that are likely to be stable at ordinary temperature and pressure? A good way to decide is to ask for which of the formulas is it possible to draw a reasonable Lewis structure (one that obeys the usual rules for drawing Lewis structures)?
On the Role of d Orbital Hybridization in the Chemistry CurriculumJohn 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. Galbraith, John Morrison. J. Chem. Educ.2007, 84, 783.
Werner and Jørgensen Bond TheoryDavid M. Whisnant, Laura Yindra This simulation begins in the period around 1870 when chemistry is beginning to be organized. The concept, introduced by Kekulé and Couper, of tetravalent carbon atoms capable of linking to each other has permitted the rise of structural concepts in organic chemistry.

Valence Bond Theory
The Evolution of Bond TheoryDavid M. Whisnant, Laura Yindra In chemistry lectures we have little time to discuss the history of chemistry. This simulation begins with the development of valence concepts in the 19th century. We will step back into the 19th century to see how theories of chemical combination changed during that time.
