In this example, it says to provide a structure of the alternating copolymer formed from the following set of monomers. Alright. So here we have our pi bond, and here we have a pi bond. We're connecting them together. So we're going to say here we start out with our CH₂, which is this CH₂.

It's connected to some rest of this polymer, so we're not going to worry about that. We're just trying to show the alternating copolymer, so the repeating unit. Alright. So now it's connected to this CH, which is connected to the chlorine, which is this. Our pi bond can act as a bridge to this other CH₂ right here.

We'll put this one here in blue. It is connected to this carbon here, which is connected to two methyls. Then we have this bond here. So then we say that there's an x number of them. We don't know, so we put the subscript n here to show that this is just one alternating copolymer in a sequence, a long polymer chain.

Alright. So this is how we display our alternating copolymer based on the two reactants given, they being vinyl chloride and isobutylene.
