AP Chemistry
2.6 Resonance and Formal Charge
2.5 Lewis Diagrams
2.2 Intramolecular Force and Potential Energy
A student models isolated \(\text{NO}_2^-\), \(\text{NO}_3^-\), and \(\text{NO}_2^+\) ions produced in an atmospheric-ion mass spectrometer. The student constructs Lewis structures that satisfy the octet rule for nitrogen and assumes that equivalent major resonance contributors contribute equally to each resonance hybrid. Which choice correctly ranks the average \(\text{N}-\text{O}\) bond lengths from greatest to least and explains the ranking?
