At the same time this acts as a base and takes away that H. And so what happens is, once this bond is broken, when the H is taken away, this reforms a pi bond between this carbon one and this carbon two to form this intermediate that contains two alcohol groups. And that's why we call it an anodial intermediate dial simply means we have two hydroxyl, two alcohol groups, one here and one here. Now, by the way, if we take this molecule and we flip it upside down, this is basically the orientation of this molecule here. So this is carbon one, carbon one, carbon two, carbon two, and carbon three, carbon three. Now let's move on to this second step. In the second step, this basically so this molecule, this nitrogen that's lost an H shown here, basically acts as a base, takes away the H from this oxygen.
