Because they push the bonding pairs down. For example in a water molecule, it has 2 lone pairs which push the 2 bonding pairs down to form a V-shaped molecule.

Hope this helps

What was VeSPER theory?

VeSPER theory, which stands for Valence Shell Electron Pair Repulsion theory, is a model used to predict the molecular geometry of molecules based on the repulsion of electron pairs in the valence shell of an atom. It helps to determine the shape of a molecule by considering the arrangement of bonding and nonbonding electron pairs around the central atom. It is a useful tool in understanding the properties and behavior of molecules in chemistry.


What is the definition of VESPR Theory?

VSEPR theory stands for Valence Shell Electron Pair Repulsion theory. It is a model used to predict the geometry of molecules based on minimizing the repulsion between electron pairs in the valence shell of an atom. By considering the repulsions between electron pairs, VSEPR theory helps determine the shape of molecules.


What is the consequence of electron-pair repulsion around an atom?

Electron-pair repulsion results in the arrangement of electron pairs around an atom in a way that maximizes the distance between them. This leads to the formation of specific molecular geometries, which in turn influence the shape and properties of the molecule.


What is a VSEPR model of molecular bonding?

The VSEPR (Valence Shell Electron Pair Repulsion) model is a theory used to predict the shape of molecules based on the repulsion between electron pairs around a central atom. It states that electron pairs will arrange themselves in a way that minimizes repulsion, leading to specific molecular geometries. By considering the number of bonding and lone pairs around the central atom, the VSEPR model helps determine the shape and bond angles of molecules.

VSEPR formulas would predict a tetrahedral shape?

The VSEPR (Valence Shell Electron Pair Repulsion) theory predicts the geometric shape of a molecule based on the repulsion between electron pairs surrounding the central atom. In a molecule with four electron pairs around the central atom, the VSEPR formula would predict a tetrahedral shape, where the bond angles are approximately 109.5 degrees.


What is repelled in the VSEPR theory?

In the VSEPR (Valence Shell Electron Pair Repulsion) theory, electron pairs around the central atom repel each other in space, leading to a molecular geometry that minimizes repulsion and maximizes stability. This repulsion between electron pairs helps determine the shape and bond angles of molecules.


What causes water molecules to have a bent shape according to VSEPR threory?

Repulsion of the unshared electron pairs (2)and the bonded pairs (2) around the central oxygen atom. Repulsion of these 4 electron pairs attempts to form a tetrahedral shape. Describing the molecular shape, we ignore the unshared electrons and just describe the shape of the molecule based on the location of the atoms, thus bent.

How do you determine the shape of molecules?

The shape of molecules is determined by the number of bonding and non-bonding electron pairs around the central atom. The VSEPR (Valence Shell Electron Pair Repulsion) theory is commonly used to predict molecular geometry based on electron pairs' repulsion. The arrangement of these electron pairs results in different molecular shapes such as linear, trigonal planar, tetrahedral, and more.
