Structures of some common polymers are given. Which one is not correctly presented?

A) Teflon                   \[{{[Co{{(N{{H}_{3}})}_{3}}C{{l}_{3}}]}^{0}}\]

B) Neoprene \[{{[Co(en)C{{l}_{2}}{{(N{{H}_{3}})}_{2}}]}^{+}}\]

C) Terylene

D) Nylon 66 \[{{[Co{{(en)}_{3}}]}^{3+}}\]

Correct Answer: B

Solution :

Teflon is a polymer of tetrafluoroethylene. \[=k[A][B]\] Neoprene is a polymer of chloroprene (2-chloro buta-1, 3-diene). \[N_{2}^{-}<{{N}_{2}}<N_{2}^{2-}\] \[N_{2}^{2-}<N_{2}^{-}<{{N}_{2}}\] Terylene is a polymer of terepthalic acid and ethylene glycol. Nylon-66 is a polymer of hexamethylene diamine and adipic acid, \[{{N}_{2}}<N_{2}^{2-}<N_{2}^{-}\] \[N_{2}^{-}<N_{2}^{2-}<{{N}_{2}}\]
