How do molecules of ethene combine together to form a poly(ethene) molecule?

Click For Summary
SUMMARY

Ethene (ethylene) molecules combine to form poly(ethene) through a process where the double bonds between carbon atoms are broken. This reaction allows the unpaired valence electrons of ethene to bond with those of adjacent ethene molecules, resulting in a long-chain polymer. The discussion highlights the importance of understanding the breaking of double bonds in polymerization. For further clarification, a video resource was shared that effectively illustrates this process.

PREREQUISITES
  • Understanding of ethene (ethylene) molecular structure
  • Knowledge of covalent bonding and valence electrons
  • Familiarity with polymerization processes
  • Basic chemistry concepts related to hydrocarbons
NEXT STEPS
  • Research the process of addition polymerization in detail
  • Explore the properties and applications of poly(ethene)
  • Study the mechanisms of breaking double bonds in organic chemistry
  • Watch educational videos on polymer chemistry for visual understanding
USEFUL FOR

Chemistry students, educators, and anyone interested in polymer science and the chemical processes involved in the formation of plastics.

hi,

i need to explain how molecules of ethene combine together to form a poly(ethene) molecule?

would it be because the double bond is broken and 2 bonds them placed on the outside of the Carbons (C)?

if this is not correct could someone please let me know where I am going wrong!

thanks!

Yes, it goes somewhat on the way you described. The double bond of ethene (ethylene) molecules are broken and the unpaired valence electron(s) get bounded with those of an other group.

See: http://en.wikipedia.org/wiki/Polyethylene

See this video, it is cute!
