Arrange the following polymers in increasing order of their intermolecular forces: (1) Nylon 6,6, Buna-S, Polythene. (2) Nylon 6, Neoprene, Polyvinyl chloride.A. `A lt B lt C `B. `B lt C lt A `C. `B gt A gt C `D. `C lt A lt B ` |

Answer» Correct Answer - B Nylon -66 is a fibre , thus has strong intermolecular forces like H-bonding . Buna-S ia an elastomer , thus has weakest intermolecular forces . Polythene is a thermoplastic polymer , thus the intermolecular forces present in polyethene are in between elastomers as fibres. Thus , the order of intermolecular forces is `B lt C lt A ` . |
