JEE Main Chemistry question

Nylons, polyesters and cotton, all possess strength due to:

(A)Intermolecule H-bondingCorrect
(B)Van der Waals' attraction
(C)Dipole-dipole interaction
(D)None of the above

Answer: (A)

Solution

Nylons (via amide N-H···O=C bonds), polyesters, and cotton (cellulose, rich in -OH groups) all derive their high tensile strength and crystallinity primarily from extensive intermolecular hydrogen bonding between adjacent polymer chains, which
