Polymers (A-level only)
Question
- A. They are formed by the addition of monomers without the loss of any small molecules.
- B. They typically have lower molecular weights than addition polymers.
- C. They release small molecules such as water during polymerization.
- D. They are always biodegradable.
Answer
They release small molecules such as water during polymerization.
Explanation
Condensation polymers are characterized by the release of small molecules, such as water, during the polymerization process, distinguishing them from addition polymers.
Common mistake
Incorrect Monomer Identification
Students often confuse the monomers used in polyesters and polyamides, leading to incorrect repeating units.
Review the structures of common monomers like ethylene glycol and terephthalic acid for polyesters, and hexamethylenediamine and adipic acid for polyamides. Practice drawing their structures to reinforce understanding.
