VSEPR is listed in the World’s largest and most authoritative dictionary database of abbreviations and acronyms.
Gillespie’s research interests include the Valence Shell Electron Pair Repulsion.
I was able to compress my in-class treatment of VSEPR theory from one-and-a-half.
In VSEPR Theory , the R stands for _____.
Valence Shell Electron Pair R _____.
The VSEPR theory is based on that ELECTRON Pairs want to get as _____ away as possible from one another.
Molecules are not always _____.
Shows the poles in a bond ~ use an arrow and arrow pointing to largest electronegativity.
VSEPR stands for valence shell electron pair repulsion theory and this name suggests how this theory works: 1.
Write down the central atom and its outer (or valence) shell electrons.
Pair each valence electron with an electron from the bonding.
VSEPR also predicts that group-2 halides such as will be linear when they are actually bent.
Quantum mechanics and atomic orbitals can give more sophisticated predictions when VSEPR is inadequate.
Solved Example for You.
Q: On the basis of VSEPR theory explain the structure of NH 3 molecule.
Ans: In ammonia, N is the central atom.

In 1956, British scientists R.
Gillespie and R.
Nyholm recognized that the current model for explaining bond angles did not work well.
The theory at that time relied on hybrid orbitals to explain all aspects of bonding.
The problem was that the theory gave incorrect prediction of bond angles for many compounds.
VSEPR stands for valence shell electron-pair repulsion and it is a pretty long name which sometimes makes student think that this is a very complicated subject but I#ll try to convince you in this video that it is not so bad.
Valence shell electron-pair repulsion -the key word here is the repulsion.
VSEPR stands for Valence Shell Electron Pair Repulsion theory.
It is a common sense type treatment of how repulsive electron regions might prefer to orient themselves in 3D space.
Here’s a surprise – they want to get as far away from each other as possible.
Definition: VSEPR is the acronym for Valence Shell Electron Pair Repulsion theory.
VESPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule’s valence electrons around a central atom.
The acronym VSEPR stands for the valence-shell electron pair repulsion model.
The model states that electron pairs will repel each other such that the shape of the molecule will adjust so that the valence electron-pairs stay as far apart from each other as possible.
