What is VSEPR Theory?
The Valence Shell Electron Pair Repulsion (VSEPR) theory is a model that predicts the shapes of molecules based on the number of electron pairs surrounding the central atom. The theory states that the electron pairs will repel each other, causing the molecule to adopt a shape that minimizes the repulsion.

How to Predict Molecular Geometry Using VSEPR?
The Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the three-dimensional shapes of molecules. The theory states that the shapes of molecules are determined by the repulsion between the electron pairs in the valence shell of the atom. The electron pairs are arranged in such a way as to minimize the repulsion between them.
The VSEPR theory can be used to predict the shapes of simple molecules, such as water, ammonia, and methane. The shapes of more complex molecules can be predicted by using the VSEPR theory to predict the shapes of the individual atoms that make up the molecule.
The VSEPR theory is based on the following assumptions:
1. Electrons repel each other.
2. The electron pairs in the valence shell of an atom repel each other.
3. The electron pairs are arranged in such a way as to minimize the repulsion between them.
The VSEPR theory can be used to predict the shapes of simple molecules, such as water, ammonia, and methane. The shapes of more complex molecules can be predicted by using the VSEPR theory to predict the shapes of the individual atoms that make up the molecule.
The VSEPR theory can be used to predict the shapes of molecules by using the following steps:
1. Draw the Lewis structure of the molecule.
2. Count the number of electron pairs in the
Linear Shape of Molecule
The molecule is linear.
Tetrahedral Shape of Molecule:
The tetrahedral shape of a molecule is determined by the number of electron pairs around the central atom. A molecule with four electron pairs around the central atom will have a tetrahedral shape.
Trigonal Bipyramid Shape of Molecule:
The trigonal bipyramid shape of a molecule is a three-dimensional shape that has six faces, each of which is a triangle. The molecule has twelve edges and eight vertices.
