Esters can be tricky to name. Why? Because we won't see the word "ester" at all in the name. So how will we name them?

Well, we can name them using both the Common and IUPAC naming system and by breaking apart the functional group in 2. Let's take a look.

Concept #1: Ester Nomenclature

  • Name as an alkyl + carboxylate

Example #1: Name the structure

Example #2: Draw the molecule

Additional Problems
