In the following sets of resonance forms, label the major and minor contributors and state which structures would be of equal energy. Add any missing resonance forms.
Here, we are going to find out the major and minor contributor structure of each molecules.
Resonance structures for a molecule would not have same energy.The stable resonance
forms are closer representations of the real molecule than less stable ones.
Here, in the first(minor) structures, all the atoms are octet except that central C atom which has nine electrons around it. On the other hand, in the second structures (major), all the carbon atoms are octet except the N atom which has nine electrons around it.
In the in the first(minor) structures, C atom has the negative charge and in the second structure N atom has negative charge...
