Chapter 26, Problem 26.1P

Interpretation Introduction

(a)

Interpretation:

From the given repeating unit the structure of polymer having $n=3$, similar to the representation in Your Turn 26.2 is to be drawn.

Concept introduction:

The repeating unit describes the connectivity that occurs over and over (repeatedly) in a polymer. A new C-C single bond is formed using the bonds that are unaccounted for on either side of the given repeating unit. The number of repeating units determines the degree of polymerization (DP). DP is the value of the subscript n.

Answer to Problem 26.1P

From the given repeating unit the structure of polymer is

Explanation of Solution

The given repeating unit is

The repeating units are shown in parentheses. A new C-C single bond is formed using the bonds that are unaccounted for on either side of the given repeating unit. In the given repeating unit four F substituents are attached to the main repeating chain. As it is given that $\text{n=3}$ there should be three repeating units joined with C-C single bond. Therefore, the structure of polymer is

Conclusion

From the given repeating unit the structure of polymer is drawn by joining repeating units by C-C single bond and the given n value.
