EEJ MAIN Chemistry QUESTION #5561
Question 1
Which of the following statements about low-density polythene (LDPE) is FALSE?
  • It is a poor conductor of electricity.
  • Its synthesis requires dioxygen or a peroxide as an initiator.
  • It is used to make buckets, dustbins, etc.✔️
  • Its synthesis requires high pressure.
Correct Answer Explanation
LDPE is made by free-radical polymerization of ethylene at high temperature (~350°C) and high pressure (~1000–2000 atm) using oxygen or a peroxide initiator. It is a poor conductor of electricity (true). LDPE is used for packaging films, bags, and squeeze bottles. Buckets and dustbins are made from HIGH-density polythene (HDPE), NOT LDPE. So option C is FALSE.
