Draw the lewis structure to find the electronic geometry and use it to determine the molecular geometry. Valence Shell Electron Pair Repulsion (VSEPR) Welcome to this introduction to VSEPR rules for the prediction of molecular shape. Valence Shell Electron Pair Repulsion. Two "election clouds" or regions of electron density around a central atom in a molecule form a linear geometry; three electron clouds form a trigonal planar geometry; four electron clouds a tetrahedral geometry; five electron clouds form a trigonal bipyramidal geometry; and six electron clouds form an octahedral geometry (Notice that five an six electron clouds correspond to situations of octet rule expansion around the central atom). Depending on how many of the clouds are lone pairs, the molecular geometry will be tetrahedral (no lone pairs), trigonal pyramidal (one lone pair), or bent (two lone pairs). The electron-pair geometries shown in Figure \(\PageIndex{3}\) describe all regions where electrons are located, bonds as well as lone pairs. The electron geometry can be obtained using VSEPR theory. NH3). 30 0 obj << /Linearized 1 /O 35 /H [ 1988 273 ] /L 19975 /E 13429 /N 1 /T 19257 >> endobj xref 30 57 0000000016 00000 n Valence shell electron pair repulsion theory, or VSEPR theory (/ ˈ v ɛ s p ər, v ə ˈ s ɛ p ər / VESP-ər,: 410 və-SEP-ər), is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. Molecular structure, which refers only to the placement of atoms in a molecule and not the electrons, is equivalent to electron-pair geometry only when there are no lone electron pairs around the central atom. This is because the movement of a bonding electron pair is limited to the region between the atoms forming the bond, while the lone pair can move more freely. Contrast this with ammonia, NH3, which does have a lone pair. 0000009173 00000 n The electron-pair geometry and molecular structure are identical, and CO2 molecules are linear. 0000003617 00000 n To minimize repulsions, four electron clouds will always adopt a tetrahedral electron geometry.
