Synthetic rubber is obtained from the polymerization of

  • A. Neoprene
  • B. Isoprene
  • C. Butadiene
  • D. Propylene

QUICK ANSWER…

B

SOLUTION…  

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:

  1. Option A is incorrect. Neoprene is already a polymer itself, made from polymerization of chloroprene.
  2. Option B is correct. Isoprene is the monomer of polyisoprene which is a type of synthetic rubber.
  3. C is incorrect. Butadiene is an ingredient used to polymerize other substances; it is not in itself a monomer.
  4. 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.

KEY-POINTS…

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.
