Question
How does the random coil shape relate to the radius of gyration of a polymer chain?
Step-by-Step Solution
Verified Answer
To determine the size of the coiled chain polymer the radius of gyration is used.
1Step 1: Definition
It is defined as the average distance between the center of mass of the molecule and the outer edge of the coil.
2Step 2: Concept
The radius of gyration of the macromolecule is more meaningful as
it gives a sense of the size of the polymer coil, instead of the end-end distance.
Hence, the square radius of gyration is the average squared distance of any point in the object (polymer coil) from its center of mass.
