NEET2018ChemistryPolymersActual
Arrange the following polymers in increasing order of their intermolecular forces. Nylon-6, 6, buna-S, polythene, neoprene
Options
- ANeoprene buna-S nylon-6, 6, polythene
- BNeoprene buna-S polythene nylon-6, 6
- CPolythene nylon- 6,6 buna- S neoprene
- DPolythene buna-S nylon-6, 6 neoprene
Correct answer
B. Neoprene buna-S polythene nylon-6, 6
Step-by-step solution
The increasing order of intermolecular forces in different polymers is elastomers < plastics fibres. So, in order to solve such problem, first classify the given polymer into the above classes and then arrange them in increasing order of forces. Neoprene (synthetic rubber) is an elastomer, buna-S is also an elastomer, polythene is plastic and nylon-6, 6 is a fibre. So, the increasing order of intermolecular forces of the given polymer is Neoprene buna-S polythene nylon- 6,6
