Which of the following statements about low density polythene is FALSE?

Options

  1. AIts synthesis required dioxygen or a peroxide initiator as a catalyst
  2. BIt is used in the manufacture of buckets, dust - bins etc.
  3. CIts synthesis requires high pressure
  4. DIt is a poor conductor of electricity

Correct answer

B. It is used in the manufacture of buckets, dust - bins etc.

Step-by-step solution

Low density polythene: It is obtained by the polymerization of ethene high pressure of 1000-2000 atm. at a temp. of 350 K to 570 K in the pressure of traces of dioxygen or a peroxide initiator (cont). Low density polythene is chemically inert and poor conductor of electricity. It is used for manufacture squeeze bottles, toys and flexible pipes.
