THanks

ethylene is the same thing as ethene... so therefore polyethylene is the same thing as polyethene or even polythene

ethylene=ethen= CH2=CH2

hope that helps

YEP.................cos of ze Americans!

 

[abdooooo!!!]

ethene is the systematic name and ethylene is the common name prefered by IUPAC (the international chemistry body). its just like poly(vinyl chloride) is the common name and poly(chloroethene) is the systematic name for PVC.

When they took out the 15% of the syllabus last October they also for some reason changed all the reference of C₂H₄ from ethene to ethylene. In an exam I don't think it would matter which one you use (at least I hope it doesn't).

It might be an idea to move this thread to the Chemistry section.

i don't think it would matter either, they can't just take a mark off just like that. but its always safe to follow what the syllabus says.
