Nylon 6,6 is a common example of a polyamide.
<em>Polyamides</em> are polymers that contain <em>repeating amide (-CO-NH-) linkages</em>.
The structure of Nylon 6,6 is
[-NH-(CH_2)_6-<u>NH-CO</u>-(CH_2)_4-CO-]_<em>n</em>
where <em>n</em> is a large number.
The numbers in the name showow that there are six carbon atoms on either side of an amide linkage.
B. is the right option. hope it will help you!
I believe the correct answer is <span>that it emphasizes the curious tone of the speaker.
The speaker is interested in what is going on on that urn, what is depicted there and why. He wants to have answers to many of his questions because he is curious, and this is why he is constantly repeating the interrogative word what.
