Question

Which of the following is/are correct?

• A. Teflon is formed by the polymerization of tetrafluoroethylene.
• B. Natural rubber is the trans form of polyisoprene.
• C. Cellulose contains only α-D-glucose linkage.
• D. Nylon-6 contains amide linkage.

Answer 1

Answer: (A), (D)

Nylon-6 contains amide linkage.

Explanation for all the options:

Option (A): Teflon is formed by polymerization of tetrafluoroethylene. It is a fluoropolymer.

Option(B): Natural rubber is the cis form of polyisoprene.

Option(C): Cellulose is a linear chain of the $\beta -1,4$ glycosidic linked D-glucose unit.

Option(D): Nylon-6 contains amide linkage. So, nylons are also called polyamides due to their characteristic amide groups in the backbone chain.

Hence options (A) and (D) are correct.
