The procedures introduced here are expected to provide an alternative to teaching Lewis structures for beginners, but not meant to be exhaustive for all molecules. For example, the central atom sulfur may exhibit an expanded octet to reduce high formal charges in the octet structure of SO4 2-. The non-octet structure for SO4 2-cannot be drawn by this proposed method. Other exceptions include PO4 3-, POCl3 etc. These non-octet structures remain challenging for teaching using the recent reported methods, as there is no clue for beginners to figure out which is the exception. It would need further studies.
