Hi guys! So in lecture, we talked about the lone pairs having a preference in placement. For example, on SF4 (sulfur tetrafluoride) the lone pair is in the equatorial plane. For the midterm, when we are asked to draw lewis structures are we going to need to place the lone pair in a certain spot with the least amount of repulsion? Say we were asked to draw the lewis structure for SF4 and we put the lone pair on the top, would we be marked down?
The midterm covers up to Chapter 3, which is Lewis structures; this means that you won't need to apply the specific molecular shapes. I also believe we won't need to apply certain placement of lone pair electrons because the VSEPR model (where we minimize e- repulsion) is in Chapter 4 and Prof. Lavelle said anyways that in any case, we won't be drawing shapes, rather naming them.
