Chemguide: Support for CIE A level Chemistry
Learning outcome 18: Carboxylic acids and derivatives
Statements 18.2.1 and 18.2.2
Statement 18.2.1: Producing esters
You have already covered this in statement 18.1.2(d). If you need to, re-read the page about esterification of carboxylic acids.
You will need some practical detail.
The syllabus also uses the term "condensation reaction". A condensation reaction is one where two molecules join together with the loss of a small molecule between them.
In this case when an alcohol reacts with an acid to give an ester, a small molecule (water) is lost when they join up.
Statement 18.2.2: Hydrolysing esters
You will find what you need on the page about hydrolysing esters. You can ignore the section on margarine at the bottom of the page.>
This reaction is also mentioned as a way of making alcohols in statement 16.1.1(f).
