Exercise II on The VSEPR Model (Shape of Larger Molecules): Solutions
Question: Draw a correct Lewis Structure for Acetic acid CH3COOH and decide on its electron domain and molecular geometries
Solution:
Based on the rules previouly mentioned, the the correct Lewis Structure of CH3COOH is:
There are 3 central atoms. Therefore, the geometry around each central atom should be assigned separately.
# electron domains | 4 | 3 | 4 |
Electron−domain Geometry | Tetrahedral | Trigonal Planar | Tetrahedral |
Molecular Geometry | Tetrahedral | Trigonal Planar | Bent |
Predicted Bond Angle | 109.5° | < 120° | < 109.5° |
