In this exercise, the basics of Valence Shell Electron Pair Repulsion (VSEPR) will be reviewed and the structures constructed using this approach will be visualized in three dimensions. Students will build molecules with geometries such as linear, trigonal planar, tetrahedral, trigonal bipyramidal, square planar, and octahedral. Students will identify the hybridizations of the various molecules constructed in the molecular modeling program. Students will utilize semiempirical methods to calculate the dipole moments of the molecular species constructed.

Various forms of asymmetry in the lengths of the bond between the central atom and sulphur, found in differing coordination environments of 1,1-dithiolate compounds involving main group atoms, have been successfully rationalized by considering both the valence shell electron pair repulsion theory and the effect of the restricted ligand bite distance.
