Question

The polymer containing strong intermolecular forces e.g. hydrogen bonding, is

• A. teflon
• B. nylon 6,6
• C. polystyrene
• D. natural rubber

Answer 1

Answer: (B)

Teflon is tetrafluoroethylene. It cannot form $H$ bonds as $H$ atom is not attached to $N,O$ or $F$.
Nylon $-6,6$ is a polyamide. It can form hydrogen bonds as $H$ atom is attached to amide $N$ atom.

Polystyrene is a polymer of styrene. It cannot form $H$ bonds as $H$ atom is not attached to $N,O$ or $F$.

Natural rubber is cis - 1, 4-polyisoprene. It cannot form H bonds as H atom is not attached to $N,O$ or $F$.
Thus, the polymer containing strong intermolecular forces (e.g. hydrogen bonding) is Nylon - 6,6 .
