2. Condensation Reactions Big IdeaTwo smaller molecules combine to form one larger molecule.A small molecule, usually water, is eliminated in the process 3. Esterification Process RCOOH +ROHEsters have distinct fruity smells.Used extensively in industry for fragrance and flavoring.The esterification reaction is also important in formation ofpolymers 4. 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. 5. Condensation Polymerization - ExamplesRecall polymers are long chains of subunits called monomers.If reacting molecules each have two functional groups that canundergo condensation, a polymer chain can form.Consider: ethane-1,2-diol andbenzene-1,4-(ethylene glycol) dicarboxylic acid 6. Formation of Terylene (Dacron)Monomer subunit would look like this. 7. Formation of Terylene (Dacron) + a bunch of H2O 8. Polymerization reactions nylon 6,6 HOOC(CH2)4COOH hexan dioic acid+ H2N(CH2)6NH2 1,6 diamino - hexane 9. Polymerization reactions nylon 6,6 10. Proteins - polypeptidesGeneral formula of an amino acid monomer 11. Proteins - polypeptides
