The molecular ion S3N, has the cyclic structure
'N
All S-N bonds are equivalent.
(a) Give six equivalent resonance hybrid Lewis diagrams
for this molecular ion.
(b) Compute the formal charges on all atoms in the
molecular ion in each of the six Lewis diagrams.
(c) Determine the charge on each atom in the polyatomic
ion, assuming that the true distribution of electrons is
the average of the six Lewis diagrams arrived at in
parts (a) and (b).
(d) An advanced calculation suggests that the actual
charge resident on each N atom is –0.375 and on
each S atom is +0.041. Show that this result is consis-
tent with the overall +1 charge on the molecular ion.
Z-S
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?
There is persuasive evidence for the brief existence of the unstable molecule OPCl.
(a) Draw a Lewis diagram for this molecule in which the octet rule is satisfied on all atoms and the formal charges on all atoms are zero.
(b) The compound OPCl reacts with oxygen to give O2PCl. Draw a Lewis diagram of O2PCl for which all formal charges are equal to zero. Draw a Lewis diagram in which the octet rule is satisfied on all atoms.
