Chemistry Question on Polymers
Which of the following is not correctly matched
A
Neoprene[-CH2-C_CL=CH-CH2]n
B
Nylon-66[-NH-(CH26-NH-CO-(CH2)-C||O-0-]n
C
Terylene[-OCH2-CH2-C||O-Oc||O]n
D
PMMA[-CH2-C-CH3-COOCH3]n
Answer
Terylene[-OCH2-CH2-C||O-Oc||O]n
Explanation
Solution
The correct option is(C): Terylene[-OCH2-CH2-C||O-Oc||O]. The corresponds to Terylene represented as [-OCH2-CH2-C||O-Oc||O] in the structure. The other options are correctly matched: (B) Nylon-6,6 corresponds to nylon polymer with repeating units. (D) PMMA - Polymethylmethacrylate is correctly represented. and (A)Neoprene. Therefore, the only mismatch among the options is with 'Terylene,' making option (C) the incorrect choice.
