As I have been looking in to how we can replace products that are derived from crude oil. A conversation on fedi,. which you can access here. You may need to scroll down to where it says

polymers are made from monomers, monomers such as ethene, styrene,  vinyl chloride et al don't *have* to come from oil. You can synthesise them from carbon dioxide & water & a few others using green energy. It's just not thermodynamically favourable or cheap.

• Ethene

• Styrene

• Vinyl Chloride

Making these from Carbon Dioxide, Water and other chemicals and utilising green energy are detailed here. However as stated this is not thermodynamically favourable or cheap. however it does show that it can be done.

• Effective pathway to convert CO2 into ethylene

For clarity, Ethene and Ethylene are the same. Ethene is the official UPAC name. cite Wikidiff

Following on from organic-chemistry-2 we have had a look at Alcohols. So will now turn some attention to plastics.

So again we can construct models of plastics in a similar way, the main difference here is that plastics are POLYMERS, which are MONOMERS chained together.

Mono – Single Poly – Multiple

So looking at the above you will notice that they are using n to indicate there is more than 1 in the chain.

So starting with ${C2H2}$ or Ethene, this becomes Polyethene when more monomers are added to the chain.

So in the video below, I construct Ethene and then, in the spirit of Blue Peter, I am then using a few more I made earlier.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.
