Arrange the following molecules in the increasing order of their intermolecular forces. (i) Terylene , Polythene , Neoprene , (ii) Polystyrene , Terylene , Buna -S

Explanation

To arrange the given molecules in the increasing order of their intermolecular forces, we need to understand the types of intermolecular forces present in each of the materials mentioned.

### Step-by-Step Solution:

1. **Identify the Types of Polymers:**
- **Terylene**: This is a type of polyester and is a fiber. It has strong intermolecular forces due to hydrogen bonding and dipole-dipole interactions.
- **Polythene**: This is a type of plastic (polyethylene) and has moderate intermolecular forces primarily due to van der Waals forces.
- **Neoprene**: This is a type of elastomer (synthetic rubber) and has the weakest intermolecular forces among the three types due to its flexible structure and weaker van der Waals forces.
