Question

The polymer containing strong intermolecular forces like hydrogen bonding is:

• A. Natural rubber
• B. Polystyrene
• C. Teflon
• D. Nylon-6,6

Answer 1

The correct option is D Nylon-6,6

A. Teflon: Teflon is tetrafluoroethylene. It does not form hydrogen bonding as in this case hydrogen atom is not attached to any electronegative atom like O, F, N etc.
B. Nylon-6,6:
Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name
It is a polyamide. It can form hydrogen bonds as the H atom is attached to amide N-atom.
C. Polystyrene: It is a repeating unit of monomer styrene. It cannot form hydrogen bonding as in this case hydrogen is not attached with any electronegative atom like O, F, N etc.
D. Natural rubber: It is cis - 1,4-polyisoprene. It cannot form H bonds as H-atom is not attached to N, O or F.
Thus, a polymer containing strong intermolecular forces like hydrogen bonding is Nylon-6,6.
