Disposable cups are made of a polymer 'polystyrene'. Polystyrene is:
Correct answer: C. An addition polymer
- A. A polyamide
- B. A condensation polymer
- C. An addition polymer
- D. A polyester
Explanation
As you can see in the above image, polystyrene is an addition polymer, where the monomers (in this, a styrene molecule) are simply linked together to form a long chain, without the formation of a secondary product so, the answer is C. Option A describes polyamide, which is a condensation polymer formed by monomers, linked by amide bonds. Option B describes condensation polymers, where the functional groups of monomers are linked together, forming a secondary product, such as H2O, in the process. Option D describes a polyester, which is a condensation polymer, formed by monomers linked by ester linkages.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
