An explanation of the molecular
An explanation of the molecular geometry for the CH3F (Fluoromethane) including a description of the CH3F bond angles. The electron geometry for the Fluoromethane is also provided.
The ideal bond angle for the Fluoromethane is 109.5° since it has a Tetrahedral molecular geometry. Experimentally we would expect the bond angle to be approximately °.
To determine the molecular geometry, or shape for a compound like CH3F, 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 CH3F we would expect it to be Tetrahedral.
