VSEPR gives the 3d shape and the bond angles within a molecule and is able to give us information in terms of the molecule's polarity and how lone pairs repulse each other, which cannot be given by simply looking at the lewis structure.
VSPER stands for Valence shell electron pair repulsion theory. While lewis structures are helpful to figure out single/double bonds and the number of lone pairs etc. VSPER takes electron pair repulsions into considerations and allows us to think about the 3D shape of the molecule.
VSEPR predicts the shapes of molecules by using the principle that regions of electron density around a central atom will tend to maximize their distance from one another. This principle leads to the various VSEPR geometries, such as trigonal bipyramidal, tetrahedral, etc. These shapes maximize the distance from each atom to the next for any given number of regions of electron density.
