hydro- : pertaining to water or fluid.
-lysis : from Latin lysis, from Ancient Greek λύσις (“‘loosening’”)
Hydrolysis - "breaking apart with water"
This article on Fischer Esterification is very useful for the more in-depth information of esters:http://www.organic-chemistry.org/namedreactions/fischer-esterification.shtm
An ester is traditionally formed by dehydration of two molecules: a carboxylic acid and an alcohol. Dehydration yields larger molecules and can be thought of as the reverse of hydrolysis, which results in smaller molecules. Carboxylic acids
are named as such since they can readily lose a proton (H+
) under relatively mild conditions. Alcohols do NOT lose protons readily and have pka's closer to that of water. For the -OH to be removed from an acohol it must be first protonated (by the carb. acid in this case) to make -OH+
. Water is a much better leaving group than -OH.
Simple answer (if you don't like learning):
From the IUPAC naming system,
the carboxylic acid part of the ester ends in -oate
Since only the alkyl chain moeity of the alcohol is attached to the ester, the aklyl chaing is placed before the -oate word.
