  1. Question 1

    Q1. High-density polyethylene (HDPE) is produced under specific conditions to ensure a linear structure. Which catalyst is essential for this process?

    • A) Organic peroxide
    • B) Ziegler-Natta catalyst
    • C) Concentrated sulfuric acid
    • D) Aluminum chloride

    Answer: Ziegler-Natta catalyst

    Explanation: Ziegler-Natta catalysts produce linear HDPE; peroxides are tempting but produce branched low-density polyethylene (LDPE) via free radical mechanism.
