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

[andyboy179]

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!
