4Esterification RCOOH + ROHEsters have distinct fruity smells.
Used extensively in industry for fragrance and flavoring.
The esterification reaction is also important in formation of polymers
5Amide formation - RCOOH + RNH2

Condensation PolymerizationRecall 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 andbenzene-1,4-(ethylene glycol)dicarboxylic acid
