Welcome to the NCERT Solutions for Class 12 Chemistry - Chapter Polymers. This page offers a step-by-step solution to the specific question from Exercise 1, Question 6:
Arrange the following polymers in increasing order of their intermolecular forces.
(i) Nylon 6, 6, Buna-S, Polythene.
(ii) Nylon 6, Neoprene, Polyvinyl chloride.
Arrange the following polymers in increasing order of their intermolecular forces.
(i) Nylon 6, 6, Buna-S, Polythene.
(ii) Nylon 6, Neoprene, Polyvinyl chloride.
Polymers can be classified on the basis of molecular forces like vander waals forces, hydrogen bonds and dipole- dipole interactions. They are classified as:
1 Elastomers- They have elastic character and have weak intermolecular forces. Example - natural rubber.
2 Fibres- They have strong hydrogen bond or dipole- dipole interactions between polymers chain. Example - nylon 66.
3 Thermoplastics- They have intermolecular forces intermediate between elastomers and fibres. Example – polythene.
4 Thermosetting polymers- They undergoes permanent change on heating. Example – bakelite.
(i) Buna − S < polythene < Nylon 6, 6
(ii) Neoprene < polyvinyl chloride < Nylon 6
The reaction between A and B is first order with respect to A and zero order with respect to B. Fill in the blanks in the following table:
| Experiment |
A/ mol L - 1 |
B/ mol L - 1 |
Initial rate/mol L - 1 min - 1 |
| I | 0.1 | 0.1 |
2.0 × 10 - 2 |
| II | -- | 0.2 |
4.0 × 10 - 2 |
| III | 0.4 | 0.4 | -- |
| IV | -- | 0.2 |
2.0 × 10 - 2 |
