Document Summary

Molecular shapes: the shape of a molecule plays an important role in its reactivity, by noting the number of bonding and nonbonding electron pairs we can easily predict the shape of the molecule. Electron domains: we can refer to the electron pairs as electron domains. In a double or triple bond, all electrons shared between those two atoms are on the same side of the central atom; therefore, they count as one electron domain. Valence shell electron pair repulsion theory (vsepr: the best arrangement of a given number of electron domains is the one that minimizes the repulsions among them. Electron-domain geometries: all one must do is count the number of electron domains in the lewis structure, the geometry will be that which corresponds to the number of electron domains. In the linear domain, there is only one molecular geometry: linear.
