Structures of some common polymers are given. Which one is not correctly presented ?
Options
- ATeflon
- BNeoprene
- CTerylene
- DNylon 66 \left[\mathrm{NH}\left(\mathrm{CH}_2\right)_6 \mathrm{NHCO}\left(\mathrm{CH}_2\right)_4-\mathrm{CO}-\right]_{\mathrm{n}}
Correct answer
B. Neoprene
Step-by-step solution
(a) Teflon is a polymer of tetrafluoroethylene.
(b) Neoprene is a polymer of chloroprene (2-chloro buta-1, 3-diene).
(c) Terylene is a polymer of terepthalic acid and ethylene glycol.
(d) Nylon-66 is a polymer of hexamethylene diamine and adipic acid. \mathrm{nH}}_{2} \mathrm{~N}\left(\mathrm{CH}}_{2}\right)_6 \mathrm{NH}}_{2}+ \mathrm{nHOOC}-\left(\mathrm{CH}}_{2}\right)_4
