Question 1

High-Density Polyethylene (HDPE) is extensively utilized in industrial chemistry for the production of rigid articles such as fuel tanks, milk jugs, and detergent bottles. Which of the following intrinsic properties is the primary reason for HDPE's suitability for these applications, distinguishing it from Low-Density Polyethylene (LDPE)?

Accepted Answer

B. Its high degree of crystallinity, resulting in greater stiffness, tensile strength, and chemical resistance. — The primary reason for HDPE's suitability for rigid containers is its high degree of crystallinity. Unlike LDPE, HDPE has minimal branching, allowing its polymer chains to pack closely together, leading to stronger intermolecular forces, which results in greater stiffness, higher tensile strength, and improved chemical resistance. Option A is incorrect as HDPE is typically opaque or translucent. Option C describes properties more characteristic of LDPE, not HDPE. Option D is incorrect because HDPE has a higher density than LDPE, and while lightweight, the key property for rigidity is its cryst
