In nylon-66, the first and second numbers (i.e., 6) respectively designate the number of carbon atoms present in the_________________?
Correct answer: D. Hexamethylene diamine and the adipic acid
- A. Hexamethylene diamine and the ring
- B. None of these
- C. Adipic acid and the ring
- D. Hexamethylene diamine and the adipic acid
Explanation
The two sixes in nylon-6,6 indicate six carbon atoms in each monomer: hexamethylene diamine and adipic acid. The numbers do not refer to a ring structure.
