In this problem, we have these reactants and we're asked for a product.
00:05
So first, let's draw out our carboxylic acid.
00:10
And then i'm going to go through our mechanism.
00:15
So first, our carbonyl oxygen takes a hydrogen.
00:26
So we get this positively charged oxygen.
00:29
And we have a resonant structure here.
00:37
And this puts a positive charge on carbon.
00:41
And now one of our electrons, from an oxygen can come attack at that positive site.
01:03
And this oxygen is positively charged.
01:07
Then we have a proton shuffle.
01:10
One of the oxygens here will take this hydrogen...
