An explanation of the molecular geometry for the CHF3 (Trifluoromethane) including a description of the CHF3 bond angles. The electron geometry for the Trifluoromethane is also provided. • The ideal bond angle for the Trifluoromethane is 109.5° since it has a Tetrahedral molecular geometry. Experimentally we would expect the bond angle to be slightly different due to the electronegativity difference between the H and F atoms. • To determine the molecular geometry, or shape for a compound like CHF3, we complete the following steps: • 1) Draw the Lewis Structure for the compound. • 2) Predict how the atoms and lone pairs will spread out when the repel each other. • 3) Use a chart based on steric number (like the one in the video) or use the AXN notation to find the molecular shape. This will be determined by the number of atoms and lone pairs attached to the central atom. • If you are trying to find the electron geometry for CHF3 we would expect it to be Tetrahedral. • Helpful Resources: • • How to Draw Lewis Structures: • How to Draw Lewis Structures: Five Ea... • • Molecular Geometry and VSEPR Explained: • Molecular Geometry: Rules, Examples, ... • • Molecular Geo App: https://phet.colorado.edu/sims/html/m... • Get more chemistry help at http://www.breslyn.org • Drawing/writing done in InkScape.
