MCQ
The natural rubber is the polymer of:
  • A
    $1, 3 -$ butadiene
  • B
    Polyamide
  • ✓
    Isoprene
  • D
    None of the above
✓

Answer

Correct option: C.
Isoprene
The monomer of natural rubber is Isoprene. Polyisoprene, a polymer of isoprene $\left(\mathrm{C}_5 \mathrm{H}_8\right)$ that is the primary chemical constituent of natural rubber.
The chemical structure of isoprene can be represented as $\mathrm{CH}_2=\mathrm{C}\left(\mathrm{CH}_3\right)-\mathrm{CH}=\mathrm{CH}_2$.
