Question
- A. It produces small molecules as by-products.
- B. It only involves unsaturated monomers.
- C. It requires high temperatures and pressures.
- D. It results in the formation of addition polymers.
Answer
It produces small molecules as by-products.
Explanation
Condensation polymerisation involves the reaction of monomers with the elimination of small molecules, such as water or methanol, as by-products. This distinguishes it from addition polymerisation, which does not produce by-products.
Common mistake
Confusing Polymer Types
Students often confuse addition polymers with condensation polymers, thinking they are the same type of reaction.
Addition polymers are formed through the addition of monomers with double bonds, while condensation polymers are formed by the reaction of monomers that release small molecules like water. Remember to identify the type of reaction based on the monomers involved.
