Which of the following has the weakest intermolecular forces ?
Correct answer: B. Polyisoprene
- A. Nylon-66
- B. Polyisoprene
- C. Polystyrene
- D. Bakelite
Explanation
Polyisoprene is a nonpolar elastomer with relatively weak dispersion forces between chains. Nylon-66 has strong hydrogen bonding, while Bakelite is cross-linked and polystyrene has stronger chain interactions than polyisoprene.
