Document Summary

10. 2 vespr theory: the five basic shapes (400-403) Valence shell electron pair repulsion (vespr) theory: allows prediction of shapes of molecules based on idea that electrons- either as lone pairs or as bonding pairs- repel one another. Based on idea that electron groups repel one another through coulombic forces. Electron groups: lone pairs, single bonds, multiple bonds, or lone electrons in a molecule repulsions between electron groups on interior atoms of a molecule determine geometry of molecule. Preferred geometry of a molecule is one where electron groups have max separation (min energy) possible for molecules with one interior (central) atom, molecular geometry depends on. Number of electron groups around central atom. Molecules that form only 2 single bonds, with no lo(cid:374)e pai(cid:396)s, (cid:396)a(cid:396)e (cid:271)e(cid:272)ause the(cid:455) do(cid:374)"t follo(cid:449) o(cid:272)tet (cid:396)ule. Double bond contains more electron density than single bond, exerts slightly greater repulsion on single bonds. Octahedral geometry: molecular geometry of 7 atoms with 90 bond angles.
