document Molecular Geometry
VISIT THE MODELS  360 SITE AT THE CHEMED DL! (search for acetic acid to get started)   When determining the shape of a molecule the basic premise is that groups of electrons surrounding an atom are repelled as far as possible from each other to minimize the overall...

document Valence Shell Electron Pair Repulsion (VSEPR) Theory
VISIT THE MODE LS 360 SITE AT THE CHEMED DL! (search for acetylene, acetic acid, and methane to get started)   Valence shell electron pair repulsion (VSEPR) theory is a model in chemistry used to predict the 3D shape of individual molecules based upon the extent of...

document Molecular Dipole Moments
Once the 3-dimensional shape of a molecule is known, the molecular dipole, or overall electron distribution in the molecule, can be determined by adding together the vectors of the individual bond dipoles.  Note that just because a molecule has polar bonds, it doesn't...
