16.4 Naming Esters
Esters such as ethyl butanoate provide the odor and flavor of many fruits, such as pineapples.
Learning Goal Write the IUPAC and common names for esters; draw condensed and line-angle structural formulas.
Slide2Naming Esters
The name of an ester consists of two words:
1. The first word indicates the alkyl
part
f
rom the
alcohol.2. The second word is the carboxylate name of the carboxylic acid.
Slide3Naming Esters
Esters have IUPAC
and common names:

Slide10Esters in Fruits
Many of the fragrances of perfumes and flowers and the flavors of fruits are due to esters.
Small esters are volatile, so we can smell them, and they are soluble in water, so we can taste them.The odor of grapes is due to ethyl heptanoate.
