And what we want to show in this diagram is the fact that we have resonance stabilization in the following region. So this is not the only lewis dot structure that we can draw. We can also draw another lewis dot structure for this same structure. In particular, the following structure. And the way that we go from this truck to this structure is by moving these two electrons into the following pi bond. So these two lone pair of electrons can form a pi bond between the carbon and the nitrogen.
