Question

Polythene is industrially prepared by the polymerisation of–
(A) methane
(B) styrene
(C) acetylene
(D) ethylene

Answer 1

Ethylene is the answer . U can refer class 11 as well as class 12 text book.

Answer 2

Polythene is industrially prepared by the polymerisation of D). ethylene

• Ethephon (2-chloroethyl phosphonic acid) is a widely used chemical replacement for ethylene treatment in many experiments.
• The conversion of ethylene takes place at higher pHs.Thus, ethylene can be easily prepared by hydrolyzing in buffered conditions.
• For industrial production, ethylene can be prepared by ethanol dehydration however, the reaction takes place under harsh conditions and further purification is extremely needed to cut out any harmful effects.
• Gas collected from the ethanol dehydration gives multiple hydrocarbon species that can be detected by the FID -flame ionization detector
