Alright guys, let's go ahead and figure out what's going on here, here we have our, how many carbons 1, 2, 3, 4 with our O coming off of the middle carbon, right? And it's got negative charge because it's got only one bond and 3 lone pairs, right? So guys, What's going to happen here? Well, we can go ahead and compare our pka's, right? pKa for water, we know is 15.7 and for alcohol it would be sixteen, right? So guys these are really close to each other. So, do you expect to find a single headed arrow like that, just one direction? probably not, right? We're going to have some kind of equilibrium going on, so it might look something like that, so guys what's going to happen here is that this is going to come in, grab this hydrogen, right? And let me go ahead and draw in my bonds explicitly and then we're going to kick these electrons onto this oxygen, so then we're going to end up with this, when it looks like this with our OH and then we're going to have our OH negative, alright? Let's move on.
