Chemical bonding — practice question

This polymer has the repeat unit shown below. It is formed from two different monomers. $\left( {-\text{CH}_2-\text{CHCl}-\text{CH}_2-\text{CH}=\text{CH}-\text{CH}_2-} \right)_n$ Which two monomers could be combined to produce this polymer?

  • A$\text{CH}_2=\text{CHCl}$ and $\text{CH}_2=\text{CH}_2$
  • B$\text{CH}_2=\text{CHCl}$ and $\text{CH}_2=\text{CHCH}=\text{CH}_2$
  • C$\text{CH}_3\text{CH}_2\text{Cl}$ and $\text{CH}_3\text{CH}=\text{CHCH}_3$
  • D$\text{CH}_3\text{CH}=\text{CHCH}_3$ and $\text{CH}_2=\text{CHCl}$
