VSEPR Theory 06/10/99 Based on Lewis structures we can know the shape or “geometry” of molecules The theory that predicts geometry (based on Lewis structures) is abbreviated VSEPR VSEPR (pronounced “vesper”) stands for Valence Shell Electron Pair Repulsion VSEPR, as the name suggests, predicts geometry based on the repulsion of electron pairs (in bonds or by themselves) Electrons around the central nucleus repel each other. Thus, resulting structures have atoms maximally spread out (balloon demo)

VSEPR overview 06/10/99 The balloons represent electron clouds. At the end of each balloon will be a peripheral atom. The balloons meet at a central atom. Each shape containing 2-6 peripheral atoms has a name (you will have to know these) Sometimes the molecules are represented by AXY, where Y is the # of peripheral atoms AX2 = linear AX3 = planar triangular AX4 = tetrahedral (tetra = 4 faces) AX5 = trigonal bipyramidal (2 pyramids) AX6 = octahedral (octa = 8 faces) Work on handout (follow instructions on sheet)
