Resonance Forms Question (b) Draw two resonance forms for nitrite ion, NO2−. What can you say about the geometry of this molecule (linear or bent)? (Hint: Consider the effect of electron repulsion exerted by the lone pair on nitrogen.)

Question (b) Draw two resonance forms for nitrite ion, NO2−. What can you
say about the geometry of this molecule (linear or bent)?
(Hint: Consider the effect of electron repulsion exerted by the lone pair on nitrogen.)
(c) The possibility of valence-shell expansion increases the number of feasible
resonance forms, and it is often difficult to decide on one that is “best.” One
criterion that is used is whether the Lewis structure predicts bond lengths and
bond angles with reasonable accuracy. Draw Lewis octet and valence-shellexpanded resonance forms for SO2(OSO).
Considering the Lewis structure for SO (Exercise 1-8), its experimental bond length of
1.48Å, and the measured S–O distance in SO2 of 1.43Å, which one of the various structures would you consider “best”.
Explain your answer in depth, clarity and with details and in a step-by-step fashion.
