Non bonded pairs have a higher force of repulsion than bonded pairs, as the bonded pairs also feel the pull of another positive nucleus. The shape of a molecule is distorted. 2 example - NH3 (one lone pair) & H2O (2 lone pairs). NH3 is trigonal pyramidal while H2O is bent.
The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
Lone electron pairs give the geometry a triangular base.
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.

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.
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.
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.
VSEPR theory is a model that predicts the three-dimensional molecular geometry of molecules based on the repulsion between electron pairs in the valence shell of an atom. It helps to determine the shape of molecules by considering the number of bonding and nonbonding electron pairs around the central atom.
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.
the lone pair on electron like nh3 make molecule good donor.
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.
The VSEPR theory allows us to determine the molecular geometry of a molecule based on the number of electron pairs around the central atom. It helps predict the shape of molecules by minimizing electron pair repulsion. This theory is useful in understanding the spatial arrangement of atoms in molecules and their properties.
Pi electron pairs are electron pairs residing in the p orbital (as in s, p, d, f). This is the electron orbital responsible for double bonds and conjugated molecules according to molecular orbital theory.
The electron pairs repel one another. The electron pairs can be in chemical bonds or be present as "lone pairs". This is the basis of VSEPR theory proposed by Gillespie and Nyholm. Who both shared the first name of Ronald! (British readers may see the humour in that )
To determine the hybridization of an atom, you can look at the number of electron groups around the atom. The hybridization is determined by the number of electron groups, which can be bonding pairs or lone pairs. The most common types of hybridization are sp, sp2, and sp3, which correspond to one, two, and three electron groups, respectively. By counting the electron groups, you can determine the hybridization of the atom.
