Chemistry - Polymer Question with Solution | TestHub

The polymer that resembles wool and is used as its substitute in making blankets, sweaters, etc., is Polyacrylonitrile (PAN), also known commercially as Orlon or Acrilan.

The monomer used to prepare Polyacrylonitrile is acrylonitrile, which has the chemical formula ${\mathrm{CH}}_2=\mathrm{CHCN}$.

Other options:
${\mathrm{F}}_2\mathrm{C}={\mathrm{CF}}_2$ is tetrafluoroethylene, the monomer for Teflon.
${\mathrm{H}}_2\mathrm{C}=\mathrm{CHCl}$ is vinyl chloride, the monomer for PVC.
The image shows chloroprene, the monomer for neoprene rubber.

Answer: ${\mathrm{CH}}_2=\mathrm{CHCN}$
