Background:
- The Valence Shell Electron Pair Repulsion (VSEPR) Theory helps us to predict the shape (or molecular geometry) of molecules. 3-D models are
helpful representations in seeing what these molecules really look like. A molecule’s shape will often determine its function and use.
- Lewis structures show bonding in molecules: a straight line shows a bonding pair (shared pair) of electrons, and two dots represent a lone pair, or
non-bonding pairs of electrons.
- Molecules can be arranged in the following molecular shapes:
