Identify the correctly matched pairs from the following set
Identify the correctly matched pairs from the following set
Show Hint
Nylon-6 = condensation homopolymer.
Terylene (PET) = condensation copolymer.
Addition polymers do not contain elimination products like water or HCl.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Analyse Statement I.
\[ ...NHCONHCH_2... \] contains amide linkage \[ (-CONH-) \] Such polymers are produced by condensation reactions. Hence it cannot be an addition copolymer. Statement I is incorrect.
Step 2: Analyse Statement II.
\[ [-CO-(CH_2)_5-NH-]_n \] This is Nylon-6. It is formed from a single monomer (caprolactam). Therefore it is a condensation homopolymer. Statement II is correct.
Step 3: Analyse Statement III.
\[ [-OCH_2CH_2OOC-C_6H_4-CO-]_n \] This is Terylene (PET). Prepared from: \[ HOCH_2CH_2OH \] and \[ HOOC-C_6H_4-COOH \] Two different monomers are involved. Hence it is a condensation copolymer. Statement III is correct.
Step 4: Determine the correct combination.
Only Statements II and III are correct. \[ \boxed{\text{Answer = (D)}} \]
