Experimentally we would expect the bond angle to be approximately 120°.To determine the molecular geometry, or shape for a compound like BF3, we complete the following steps:1) Draw the Lewis Structure for the compound (for BF3: https://youtu.be/JecuOoa12gQ).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. Therefore BF 3 is nonpolar. More info on boron trifluoride (BF 3) at wikipedia: Wikipedia Boron Trifluoride. Electron geometry for this is tetrahedral. > a) "BrF"_5 The Lewis structure is The central "Br" atom has six electron domains, so the electron geometry is octahedral.
