Q14 / 84 · NTA Abhyas (NEET) 2020 · Chemistry · Polymers
Which of the following statements about low density polythene is false?
- Correct answerAIt is used in the manufacture of buckets, dust-bins etc.
- BIts synthesis requires high pressure
- CIt is a poor conductor of electricity
- DIts synthesis requires dioxygen or a peroxide initiator as a catalyst.
Solution
Low density polythene: It is obtained by the polymerisation of ethene under 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.
Low density polythene is chemically inert and poor conductor of electricity. It is used for manufacture squeeze bottles, toys and flexible pipes.
Hence, the correct answer is option: 'A'.
