All right, so here we want to order these in decreasing acidity.
00:05
We want to see which one of these are more stable and less stable, or more acidic or less acidic.
00:12
And so we can go ahead and draw these out.
00:15
And so what we're going to look at is the stability of the conjugate base.
00:23
So if we pull a proton off, it's going to deposit the electrons from that carbon hydrogen bond onto the structure and what we left with an anion.
00:31
So we can look at the stability of that anion in each of these different structures.
00:37
So if we pull the same proton off in each of the places, we are left with these structures.
01:02
And so if we look at the two structures that have a pie system, we can check for resonance, because resonance could be possible within a pie system like this.
01:16
And so if we check if we can move these electrons, if we deposit those electrons down, then the electrons in this bond can move over.
01:31
And this shows us that that negative charge can be distributed across those different atoms, which makes our base a little bit more stable than this one.
01:40
Now if we look at the third structure, we can do something similar.
01:47
However, we have two options now...
