The correct options are
A Nylon fibers have higher tensile strength than teylene fibres.
B 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.
