Synthetic rubber is obtained from the polymerization of
- A. Neoprene
- B. Isoprene
- C. Butadiene
- D. Propylene
Synthetic rubber is obtained from the polymerization of Isoprene.
Polymerization of isoprene produces synthetic rubber popularly called polyisoprene.
Now for the right answer to the above question:
- Option A is incorrect. Neoprene is already a polymer itself, made from polymerization of chloroprene.
- Option B is correct. Isoprene is the monomer of polyisoprene which is a type of synthetic rubber.
- C is incorrect. Butadiene is an ingredient used to polymerize other substances; it is not in itself a monomer.
- D is not the correct answer. Propylene is a monomer which is usually polymerized to form polypropylene. Now, polypropylene is a thermoplastic substance and not synthetic rubber.
You may please note these/this:
- Although butadiene can be used to polymerize some substance, it is not in itself a complete monomer.
- Propylene can be polymerized, but it does not form synthetic rubber.
