Molecular Geometries
Molecular shapes, or geometries, are critical to molecular recognition and function.
The Lewis structure of carbon tetrachloride:
- The bond angles
- The bond lengths
In carbon tetrachloride:
- Each C-Cl bond length is 1.78Å
- Each Cl-C-Cl bond angle is 109.5°
Carbon tetrachloride is tetrahedral in structure:
- Provides information about connectivities
- Provides information about valence orbitals
- Provides information about bond character
However, the Lewis structure provides no information about the shape of the molecule
The structure of a molecule is defined by:
