This question is about haloalkanes and polymers.
Freon-12 is a CFC with the molecular formula CF2Cl2\text{CF}_2\text{Cl}_2CF2Cl2. In the upper atmosphere, the presence of Freon-12 can lead to ozone depletion.
Explain, with the aid of equations, how Freon-12 can lead to this ozone depletion. Use 'dots' (∙\bullet∙) to show the position of unpaired electrons.
An oligomer is a polymer with a low molecular mass and a small number of repeat units. An oligomer made from chlorotrifluoroethene is used in specialized chemical-resistant seals.
Draw the repeat unit of this oligomer.
The viscosity of this sealant can be increased by increasing the length of the oligomer chains. Explain this statement in terms of intermolecular forces.
A polymer can be made from the monomers:
Draw the structures of these monomers and one repeat unit of the polymer.
