Nylon is classified as a condensation polymer because during its formation
Correct answer: C. a small molecule such as water or hydrogen chloride is eliminated at each linkage
- A. no by product is formed
- B. the monomers contain double bonds that open
- C. a small molecule such as water or hydrogen chloride is eliminated at each linkage
- D. the polymer is condensed from a gas
Explanation
A diamine and a dicarboxylic acid react so that an amide linkage forms and water is expelled at each join, which is why the polymer contains fewer atoms than the sum of its monomers. Nylon is a polyamide, and terylene, formed from a diol and a diacid, is the analogous polyester. Every condensation monomer needs two functional groups so the chain can grow at both ends.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
