How to pronounce “double bond” in English

These correspond to stretching a double bond between a carbon and a nitrogen and a single bond between a nitrogen and an oxygen.

What makes it so reactive is you have a double bond attached to a nitrile group and an ester group.

And the unique part about that is the chemistry of those groups that make that double bond so electron deficient.

What likely happened is they grabbed onto a carbon atom from a rubber chain, breaking its double bond and attached itself.

So one of them probably grabbed onto a carbon from a different TFE molecule, breaking its double bond.

In the presence of a negative ion, the carbon double bond breaks and four single bonds form.

If you zoom in on a chain, you'll see that the monomers are attached to each other on the same side of the double bond.

Then with another free bonding site, it grabbed onto a carbon atom from a different rubber chain, breaking its double bond and linking the two rubber chains together.

- But with synthetic rubber, it's easy for monomers to attach on the opposite side of the double bond.

- To polymerize TFE into Teflon, you can add a reactive atom or molecule that will hijack the first carbon double bond
