Which of the following functional groups is primarily responsible for the high tensile strength, hig — Polymers Chemistry Question

💡 Solution & Explanation

Fibres are thread-forming solids with high tensile strength. This is attributed to strong intermolecular forces like hydrogen bonding. In polyamides (Nylons), these strong hydrogen bonds form between the hydrogen of the $-NH$ group and the oxygen of the $-C=O$ group of adjacent chains, leading to close packing and a crystalline nature.
