The following ions are best described with resonance structures. Draw the resonance structures, and using the formal charge arguments, predict the best Lewis structure for each ion:

2. \({\rm{CN}}{{\rm{O}}^{\rm{ - }}}\)
ANSWER:Step 1 of 8
Resonance structures are formed when electrons shift the positions over the available atoms. The movement of these electrons over a set of atoms provides stability to the molecule as a whole.
The formal charge on an atom in a molecule is derived as:
\(FC = V - \left( {N + \dfrac{B}{2}} \right)\)
Where V represents the atoms valency, N represents the electron count existing as lone pairs and B represents the electron count existing as bond pairs.
