Question

Which of the following statements are correct about Nylon - $6,6$ ?

• A. Nylon fibers have higher tensile strength than teylene fibres.
• B. Nylon fibers have lower tensile strength than terylene fibres.
• C. In nylon, there is strong intermolecular H-bonding, while in terylene there is weak dipole-dipole interaction.
• D. In nylon, there is weak dipole-dipole interaction, while in terylene there is strong intermolecular H-bonding.

Answer 1

Answer: (A), (C)

Nylon fibers have higher tensile strength than teylene fibres.
In nylon, there is strong intermolecular H-bonding, while in terylene there is weak dipole-dipole interaction.

Nylon - $6,6$ has high mechanical strength and superior resistance to wear and organic chemicals.
It has more than double the strength and stiffness of unreinforced nylon.
Nylon has $-NH-CO-$ bond which results in intermolecular H-bonding.
Terlyene has no H-bonding and has only weak dipole-dipole interactions and hence, nylon - $6,6$ has higher tensile strength compared to that of terylene.
