Ethylene is a monomer of polyethylene that is widely used as raw material for manufacturing plastics. It can be polymerized into two different classes: HDPE and LDPE. The following choices are the differences of HDPE and LDPE except:
Correct answer: D. Type of polymerization
- A. The density
- B. The branching of ethylene
- C. Reaction conditions
- D. Type of polymerization
Explanation
Ethylene is a monomer of polyethylene that is widely used as raw material for manufacturing plastics. It can be polymerized into two different classes: HDPE and LDPE. There are many differences between HDPE and LDPE but they differ highly in density, branching of ethylene, and reaction conditions such as temperature, pressure, and catalysts. On the other hand, they both undergo chain-growth polymerization or addition polymerization.

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.
