What is V.S.P.R theory?

Answer 1

Its actually called VSEPR (valence shell electron pair repulsion). The theory is simply a model to describe how molecules are oriented in three dimensions. Like where each bong is pointing and where the electrons are. It goes on the basis that electrons will repel each other, and get as far away from each other as possible. Take for example methane (CH4). the carbon has 4 identical hydrogens attached to it, each with a single bond. The single bond means the carbon and hydrogen are sharing a pair of electrons. The electrons of each hydrogen will push the hydrogen apart, creating a tetrahedral shape. The VSEPR theory provides method for predicting this for all sorts of molecules. included in it is bond angles.

Google VSEPR if youre looking for more specific orientations (planar, trigonal planar, tetrahedral, square based pyramid, etc).

Answer 2

V.S.P.R. theory, or Valence Shell Electron Pair Repulsion theory, is a model used in chemistry to predict the shape of molecules based on the arrangement of electron pairs around the central atom. It states that electron pairs in the valence shell of an atom repel each other and will arrange themselves as far apart as possible to minimize repulsion, resulting in specific molecular geometries.

Answer 3

Valance Shell Electron Pair Repulsion

It's used to predict the shape of individual molecules.
