Thank you!

What are your thoughts?

I know the double bond has to break into single bonds but I’m not sure how to determine where the position of the branching is?

Do you lay out every alkene addition polymer equation the same way?
i.e. with the C=C horizontally with the four attached groups above and below their respective C atoms? And then show the polymer with the same arrangement of atoms?
Like this: https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.savemyexams.com%2Figcse%2Fchemistry%2Fcie%2F23%2Frevision-notes%2F11-organic-chemistry%2F11-3-polymers%2F11-3-2-addition--condensation-polymers%2F&psig=AOvVaw32Sb8W-5hx_Y09x0UqMew9&ust=1712681563859000&source=images&cd=vfe&opi=89978449&ved=0CBIQjRxqFwoTCNj5kJeKs4UDFQAAAAAdAAAAABAE
Can you do the same for cyclohexene?

But im not sure how the double bond would break here? Normally if it was ethane or propene etc, it would be arranged as you said with the atoms above and below c-c but i dont know how to do this for the cycloalkane?

Is it C?

Yes

I guess the easy way to look at it is that when polymerisation occurs, the double bond breaks so that two carbon atoms have unpaired electrons. These two carbon atoms will always be side by side (as they share the double bond) so the branches will also be side by side. This is only the case is part C.
