A stable triatomic molecule can be formed that contains one atom each of nitrogen, sulfur, and fluorine. Three bonding structures are possible, depending on which is the central atom: NSF, SNF, and SFN.
(a) Write a Lewis diagram for each of these molecules, indicating the formal charge on each atom.
(b) Often, the structure with the least separation of formal charge is the most stable. Is this statement consistent with the observed structure for this molecule— namely, NSF, which has a central sulfur atom?
(c) Does consideration of the electronegativities of N, S, and F from Figure 3.18 help rationalize this observed structure? Explain. 100. The gas
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, HaPO, , in which the H atoms are bonded
to O atoms. (a) What is the predicted dominant Lewis structure if satisfying the
octet rule is the top eriterion? (b) What is the predicted dominant Lewis structure if
achieving the best formal charges is the top criterion?
