La théorie VSEPR (sigle de l'anglais Valence Shell Electron Pair Repulsion, en français RPECV : « répulsion des paires électroniques de la couche de valence ») est une méthode destinée à prédire la géométrie des molécules en se basant sur la théorie de la répulsion des électrons de la couche de valence La méthode VSEPR permet la plupart du temps la prédiction correcte de l'arrangement local des paires d'électrons autour d'un atome lorsque celui-ci peut être choisi sans ambiguïté comme atome central. En revanche, son application est beaucoup plus problématique quand il s'agit de prévoir la géométrie globale de molécules complexes. Ainsi il n'est pas possible de prévoir la.

On va prendre le plus simple CO2, O est le plus électronégatif, il y a donc un excès de charge - sur O et + sur C. Le vecteur dipôle est dirigé de la charge - vers la charge +. avec q>0. Comme CO2 est linéaire, les deux vecteurs CO sont opposés et se compensent, donc non polaire. Si on prend H2O, même chose, sauf que cette fois ci la molécule est coudée et donc la résultante est non.

BeF 2 and BF 3 are both two-dimensional molecules, in which the atoms lie in the same plane. If we place the same restriction on methane (CH 4), we would get a square-planar geometry in which the H-C-H bond angle is 90 o. If we let this system expand into three dimensions. VSEPR only recognizes groups around the central atom. Thus the lone pairs on the oxygen atoms do not influence the molecular geometry.

Valence shell electron pair repulsion (VSEPR) rules are a model used to predict the shape of individual molecules based upon the extent of electron-pair electrostatic repulsion. The premise of VSEPR is that the valence electron pairs surrounding an atom mutually repel each other, and will therefore adopt an arrangement that minimizes this repulsion, thus determining the molecular geometry The VSEPR Model does not allow one to predict how much smaller the bond angle will be, but one can predict the HOH bond angle is . 109.5°. water.

According to VSEPR. VSEPR* is a model that is pretty good at predicting the general features, if not the details, of the structures of polyatomic molecules. The basic idea is that when bonds form, they create a region of relatively high electron density - places where the electrons spend most of their time.

But ::O=S=O:: has only four valence electrons on sulfur. The lone pair makes six, as in ::O=S=O:: SO2 is bent (C2v) because sulfur's VSEPR geometry is trigonal planar; the third group is the lone pair.. VSEPR calculation for water, O H 2 Water has four electron pairs and the coordination geometry of oxygen is based upon a tetrahedral arrangement of electron pairs. Since there are only two bonded groups, there are two lone pairs. Since the lone pairs are not 'seen', the shape of water is bent. The two lone pairs compress the H-O-H bond angle below the ideal tetrahedral angle to 104.5° ( I ) VSEPR Theory fails to explain isoelectronic species. Isoelectronic species are elements, ions and molecules that share the same number of electrons.

O modelo de repulsão de pares de elétrons na camada de valência (VSEPR, do inglês valence shell electron-pair repulsion) é usado para prever as formas de moléculas e íons poliatômicos. O VSEPR é baseado na ideia de que os grupos de elétrons ou eletrosferas ao redor de um átomo adotarão um arranjo que minimize as repulsões entre eles. Neste vídeo, veremos exemplos de. Double and Triple Bonds in VSEPR Theory . Molecular geometry is determined by possible locations of an electron in a valence shell, not by how many how many pairs of valence electrons are present. To see how the model works for a molecule with double bonds, consider carbon dioxide, CO 2. While carbon has four pairs of bonding electrons, there are only two places electrons can be found in this. VSEPR is a molecular geometry model that helps predict the general shape of a molecule but doesn't provide information about the length or type of bonds. VSEPR theory is not effective in molecules where the central atom is a transition metal and thus has a high atomic mass that offsets or weakens the pull of bonded valence electrons

Chemical bonding - Chemical bonding - Molecular shapes and VSEPR theory: There is a sharp distinction between ionic and covalent bonds when the geometric arrangements of atoms in compounds are considered. In essence, ionic bonding is nondirectional, whereas covalent bonding is directional. That is, in ionic compounds there is no intrinsically preferred direction in which a neighbour should lie.

VSEPR theory proposes that the geometric arrangement of terminal atoms, or groups of atoms about a central atom in a covalent compound, or charged ion, is determined solely by the repulsions between electron pairs present in the valence shell of the central atom. The number of electron pairs around the central atom can be determined by writing the Lewis structure for the molecule. The geometry. VSEPR Theory rule of thumb Electrons spread out . Lone pairs are close to atom, whereas bonding pairs shift further apart from the central atom. Due to the different amount of repulsion by the lone pair and bonding pairs, therefore: Lone Pair repulsion > Bond-Lone pair repulsion > Bond Pair repulsio Composé d'un atome de carbone et de deux atomes d'oxygène, le dioxyde de carbone (CO2) est une molécule linéaire.
