Problem: Some chemists believe that satisfaction of the octet rule should be the top criterion for choosing the dominant Lewis structure of a molecule or ion. Other chemists believe that achieving the best formal charges should be the top criterion. Consider the dihydrogen phosphate ion, H2PO4–, in which the H atoms are bonded to O atoms.What is the predicted dominant Lewis structure if achieving the best formal charges is the top criterion?
