The position of bonding and non-bonding pairs of electrons in molecules or ions with five electron domains can be predicted by identifying the arrangement with the lowest number of lone pair–lone pair 90∘ angles followed by the lowest number of 90∘ angles between lone pairs and bonding pairs.Can you use this approach to show why we observe see-saw, T-shaped and linear geometries for SF4 , ClF3 and I3− seen in this section?
