Question:
What is a starting material used to obtain viscose rayon ?
What is a starting material used to obtain viscose rayon ?
Show Hint
Viscose rayon is regenerated cellulose, made from wood pulp.
Updated On: Oct 1, 2026
- Styrene
- Cellulose
- Acrylamide
- Bisphenol
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Rayon is a semi-synthetic fibre. It is made from a natural polymer that is chemically treated and then re-formed into fibres.
Step 2: Key Formula or Approach:
Viscose rayon is also called regenerated cellulose.
Step 3: Detailed Explanation:
Wood pulp (which is mostly cellulose) is treated with NaOH and carbon disulphide to give cellulose xanthate, a viscous solution called viscose. When this is forced through a spinneret into acid, the cellulose is regenerated as fibres.
So the starting material is cellulose.
Styrene is the monomer of polystyrene. Acrylamide gives polyacrylamide. Bisphenol A is used for polycarbonates and epoxy resins. None of these gives viscose.
Final Answer:
Viscose rayon starts from cellulose, option (B). \[ \boxed{\text{Cellulose (B)}} \]
