2. Condensation Reactions – Big Idea
Two smaller molecules combine to form one larger molecule.
A small molecule, usually water, is eliminated in the process

5. Esterification Process – RCOOH +
ROH
Esters have distinct fruity smells.
Used extensively in industry for fragrance and flavoring.
The esterification reaction is also important in formation of
polymers
6. Amide formation - RCOOH + RNH2
Example 1: Sketch a diagram to show the formation of
ethyl butanoate by the process of esterification.
Example 2: Sketch a diagram to show the formation of
the amide product of a reaction between ethanol and
propylamine.
7. Condensation Polymerization -
Examples
Recall – polymers are long chains of subunits called monomers.
If reacting molecules each have two functional groups that can
undergo condensation, a polymer chain can form.
Consider:
ethane-1,2-diol and benzene-1,4-
(ethylene glycol) dicarboxylic acid
