Which statement about condensation polymers is true?

Which statement about condensation polymers is true?

• A. They are formed by linking two or more monomers with water produced
• B. They are formed by linking identical monomers without byproducts
• C. They are formed by cracking polymers
• D. They are a type of metal

Answer: (A)

Condensation polymerization involves joining monomers with the release of a small molecule, usually water. As each bond forms, a molecule such as water is produced, so the polymer grows while water is eliminated. That’s why this statement is true: it describes both the joining of two or more monomers and the water byproduct that accompanies the process. The idea of linking identical monomers without any byproducts would correspond to a different type of reaction (no small molecule is released). Cracking polymers is about breaking them down, not making them. Polymers are not metals; they’re long chains built from non-metal elements like carbon, hydrogen, oxygen, and nitrogen.
