Show Hint
Orlon is the trade name of polyacrylonitrile.
Updated On: Nov 12, 2026
- Acrolein
- Glycol
- Vinyl cyanide
- isoprene
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Orlon is a synthetic fibre that is a trade name for polyacrylonitrile (PAN).
Step 2: Monomer
It is made by addition polymerisation of acrylonitrile, \(\text{CH}_2\text{=CH-CN}\), which is also called vinyl cyanide.
Step 3: Compare the options
Acrolein is an unsaturated aldehyde, glycol is used for polyesters and isoprene is the monomer of natural rubber.
Final Answer:
The monomer of Orlon is vinyl cyanide. \[ \boxed{\text{(C) }\text{Vinyl cyanide}} \]
