Oct 09, 2021· This would make the electron geometry tetrahedral. However, this is not the molecular geometry. Two of these attachments are bonds and the other two are lone pairs. Therefore, the resulting molecular geometry is a a bent geometry. Now that we know the molecular geometry, we can determine the bond angle to be about 105 degrees from our chart.
