Two condensation polymers are made

(1) ethylene diamine + ethane-1,2-dicarboxylic acid

(2) trimethylenediamine + ethane-1,2-dicarboxylic acid if both polymers of same molecular weight are obtained then which of the following statements is/are correct?

(i) Polymer (1) is found to melt at lower temperature.

(ii) Polymer (2) is found to melt at lower temperature.

(iii) H-bonding is major factor.

View answer and explanation

Correct option: D

(ii) and (iii)

Option D ((ii) and (iii)) is correct because polymer (2) has weaker intermolecular forces due to the longer alkyl chain, leading to a lower melting temperature, and H-bonding is a major factor in condensation polymers.
