The repulsion between valence electron pairs in the outer shell of the central atom determines the shape of the molecule. You must determine the steric number (SN) — the number of bonding pairs and lone pairs about the central atom.
Lone pairs repel more than bond bonding pairs.
There are three basic steps to determining the molecular shape of a molecule:
Write the Lewis dot structure of the molecule. That gives you the steric number (SN) — the number of bond pairs and lone pairs around the central atom.
Use the SN and VSEPR theory to determine the electron pair geometry of the molecule.
Use the VSEPR shape to determine the angles between the bonding pairs
