A short fragment of a polymer chain (three repeat units, end groups shown) is drawn. Which functional group links the repeat units?

  1. AEster
  2. BUrethane
  3. CAmide
  4. DEther

Answer: C

Each link is a -CO-NH- group, an amide, so the polymer is a polyamide (nylon 6). An ester would be -CO-O-, an ether -O-, and a urethane -NH-CO-O-.
