Question

The polymer containing strong intermolecular forces like hydrogen bonding is :

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

Answer 1

The correct option is B nylon - $6,6$

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 - $6,6$.

Hence, the correct option is $B$
