When the electrons are able to flow through the neighboring pi systems, the phenomenon of resonance takes place. Resonance structures are defined as the forms of a molecule having the same chemical connectivity, but the different distribution pattern for the electrons around the structure. To determine: The different resonance structures for the NCO − ion; prediction of the best Lewis structure on the basis of the formal charge.
