And so what happens is this lone pair of electrons and this oxygen forms a pi bond. At the same time, this pipeline here between carbon one and two actually breaks. And those two electrons in the pi bond go and grab that H atom shown in blue. And this is the same H atom that was initially attached onto carbon number one. And so we see that's how the carbon moves from carbon one to carbon number two as a result of this process. So in this process, the H is temporarily transferred onto the oxygen from carbon one.
