Chapter 14, Problem 1QAP

(a)

To determine

To sketch:

The repeat unit structure of polychlorotrifluoroethylene.

Answer to Problem 1QAP

The repeat unit structure of polychlorotrifluoroethylene is sketched and shown in

Figure 2.

Explanation of Solution

The repeat unit of polychlorotrifluoroethylene is arrived from the repeat unit of polyethylene.

The repeat unit molecular structure of polyethylene is shown in Figure 1.

The repeat unit of polyethylene contains two carbon atoms and four hydrogen atoms.

The replacement of three hydrogen atoms by three fluorine atoms and one hydrogen atom by one chlorine atom gives the repeat unit molecular structure of polychlorotrifluoroethylene that is shown in Figure 2.

(b)

To determine

To sketch:

The repeat unit structure of poly (vinyl alcohol).

Answer to Problem 1QAP

The repeat unit structure of poly (vinyl alcohol)is sketched and shown in

Figure 3.

Explanation of Solution

The repeat unit of poly (vinyl alcohol)is arrived from the repeat unit of polyethylene.

The repeat unit molecular structure of polyethylene is shown in Figure 1.

The repeat unit of polyethylene contains two carbon atoms and four hydrogen atoms.

The replacement one hydrogen atom by one alcohol atom gives the repeat unit molecular structure of poly (vinyl alcohol) that is shown in Figure 3.
