The premise of the VSEPRtheory is that electron pairs located in bonds and lone pairs repel each other and will therefore adopt the geometry that places electron pairs as far apart from each other as possible.
The valence shell electron pair repulsion theory or VSEPR theory is used to predict the three-dimensional shape of a molecule. According to this theory, the molecular shape depends on the repulsion between the valence shell electron pairs of the central atom.
Enter the Valence Shell Electron Pair Repulsion (VSEPR) Theory —a simple, elegant, and surprisingly accurate model that allows us to visualize and predict molecular geometry just by looking at the atoms and their valence electrons.
In chemistry, VSEPRTheory is based on the principle that each atom in a molecule will seek a geometry that maximizes the distance between valence electron pairs, thus minimizing electron-electron repulsion.
It states that any molecule arranged in such a structure minimizes the repulsion between the lone pair and bond pair of the molecule. Let's learn more about VSEPRtheory in detail, including its postulates, limitations, and examples.
The model used to predict the shape of a molecule is known as the Valence Shell Electron Pair Repulsion Theory (often remembered by the acronym VSEPR). The model presumes that the groupings of electrons surrounding the central atom will repel each other.

VSEPRtheory is based on the idea that electron pairs around a central atom repel each other and arrange themselves to minimise repulsion, thus determining the molecular shape.
VSEPRtheoryexplains that the shapes of different molecules are a result of their bonds, lone pairs, and minimized electron repulsion between the atoms. What is VSEPRTheory? VSEPR stands for valence shell electron pair repulsion. Valence shell electrons are on the outer part of an atom.
