WebVideo transcript. Voiceover: One way to make an ester is to use a Fischer esterification reaction. So if you start with the carboxylic acid, and you add an alcohol, and a source of protons, you're gonna form your ester, and you're also going to make water in this process. WebVideo transcript. - [Lecturer] In the last video, we looked at a Fischer projection of a compound that had only one chirality center. This molecule has two, and our goal is to determine the configuration of each chirality center, so at the intersection of these lines here, we know that this is a chiral center and then we have another one down ...
