And so what we see happen is these two electrons on the nitrogen basically form a pipeline between this nitrogen, this carbon, and that breaks this pipeline here. And that Pi bond acts as a nucleophile. It basically attacks the carbon, forms a sigma bond between this carbon here and this carbon here. And what that also does is breaks this Pi bond. And the Pi bond is used to pick up this hion. And so once this addition reaction takes place, we form the following intermediate.
