Which of the following statements about low density polythene is FALSE?
Options
- AIts synthesis required dioxygen or a peroxide initiator as a catalyst
- BIt is used in the manufacture of buckets, dust - bins etc.
- CIts synthesis requires high pressure
- 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.
