discuss the role of interchain molecular interactions observed between the single chains of nylon molecules that stabilizes fiber formation (any analogy to the biological systems). Depict it by drawing it in detail !!!!!.

Expert Solution

Nylon molecules have NH group.

These NH group helps in forming interchain interaction among several nylon fbres.

The strongest non-covalent forces are hydrogen bonds, which involve a positively charged hydrogen interacting with an electronegative element. Only hydrogen that is bonded to nitrogen, oxygen, or fluorine can do it, e.g. in OH^...O, OH^...N, NH^...O, OH^...F, etc. In the case of Nylon There are NH groups that can make hydrogen bonds to the C=O groups of another chain. Each of these hydrogen bonds is worth only about 15-20 kJ/mole, compared to 300-400 kJ/mole for a covalent bond.

Hydrogen bonds (in combination with London interactions, see below) hold the DNA double helix together, and are the things that make complementary nucleotides "recognize" each other, so that DNA chains can replicate. Without these interactions, there could be no molecular basis for heredity.
