Polyacrylonitrile is used as a substitute for wool in making commercial fibres as acrilan. The structure of it is:
Show Hint
Polyacrylonitrile contains a nitrile (-CN) group attached to the polymer backbone, distinguishing it from other polymers with hydroxyl (-OH) or nitro (-NO_2) groups.

The Correct Option is C
Solution and Explanation
Polyacrylonitrile is a synthetic polymer used as a substitute for wool in textile applications under the trade name acrilan. Its repeating unit consists of a vinyl backbone with a nitrile (–CN) group attached to the carbon atom.
The structure of polyacrylonitrile is represented as: \[ \left[-CH_2 - CH-\right]_n | CN \] This nitrile group is responsible for the characteristic properties of polyacrylonitrile, including its strength and thermal stability, making it suitable as a wool substitute.
