Polymers

Polymers are naturally occurring or synthetically produced large molecules or compounds which are made up of series of repeating units called monomers. They are joined together by chemical bonds. The term polymer is coined from Greek roots meaning 'many parts' and are found almost everywhere from the plastics bags to the rubber of our tires to our DNA strands.

Question

Give the products of the reaction and name which kind of condensation reaction is involved.

This image illustrates a series of chemical reactions involving the Claisen condensation. The sequence of reactions involves the use of sodium ethoxide (NaOEt) and ethanol (EtOH) as reagents. Here’s a detailed breakdown of each step:

1. **First Reaction:**
- **Reactant:** Ethyl 3-oxobutanoate
- **Reagent:** NaOEt in EtOH
- **Product:** A new compound is produced, though not explicitly shown, typically resulting in a β-keto ester in Claisen condensations.

2. **Second Reaction:**
- **Reactants:** Ethyl 2-methyl-3-oxobutanoate and acetone
- **Reagents:** NaOEt in EtOH
- **Product:** Another product of Claisen condensation, typically involving a nucleophilic acyl substitution leading to β-diketone formation.

3. **Third Reaction:**
- **Reactant:** A previously formed β-keto ester
- **Reagent:** NaOEt in EtOH
- **Product:** The reaction yields a compound with an additional carbonyl group, often indicative of the completion of another step in a synthetic pathway.

These steps illustrate key transformations found in organic synthesis where the formation of carbon-carbon bonds is critical. Claisen condensation is commonly used to create diketones, which are versatile intermediates in the synthesis of more complex molecules.
