Common mistakes in VSEPR theory and shapes of simple molecules

Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.

Uses common four-coordinate shapes for molecules with five and six electron domains.
Uses the same tetrahedral label for molecular shape in all three cases and ignores the effect of lone pairs on both shape and bond angle.
