Arrange the following polymers in the order of increasing intermolecular forces : Nylon-6, Buna-S, Polythene

Explanation

To arrange the polymers Nylon-6, Buna-S, and Polythene in the order of increasing intermolecular forces, we need to understand the nature of these polymers and the type of intermolecular forces they exhibit.

### Step 1: Identify the Type of Each Polymer
1. **Nylon-6**: This is a type of polyamide and is classified as a fiber. Fibers typically have strong intermolecular forces due to hydrogen bonding and dipole-dipole interactions.
2. **Buna-S**: This is a synthetic rubber (an elastomer) made from styrene and butadiene. Elastomers generally have weaker intermolecular forces compared to fibers.
3. **Polythene**: This is a thermoplastic polymer. It has relatively weak van der Waals forces (dispersion forces) between the polymer chains.

### Step 2: Compare the Intermolecular Forces
