Question

A. When a polymer is formed without the loss of any small molecules
B. When a polymer is formed from the addition of unsaturated monomers
C. When a polymer formation involves the elimination of water or another small molecule
D. When a polymer is made exclusively from carbon-based monomers

Answer

When a polymer formation involves the elimination of water or another small molecule

Explanation

The term 'condensation polymer' is defined as a polymer that forms through reactions where small molecules, such as water, are eliminated. This distinguishes it from addition polymers, which do not involve such elimination. Condensation polymers are relevant in the synthesis of materials like polyesters and polyamides, where the reaction leads to the release of byproducts.

Common mistake

Distinguishing Addition and Condensation Polymers

Students often confuse addition polymers with condensation polymers, thinking they are the same because both involve multiple monomers.

Addition polymers are formed through the addition of unsaturated monomers (like alkenes) without the loss of any small molecules, while condensation polymers are formed by the reaction of monomers with the loss of small molecules (like water). Remember that addition polymers involve only C=C bonds, whereas condensation polymers involve functional groups that can react to release small molecules.
