Arrangement the following polymers in increasing order of their intermolecular forces. Nylon `6,6` Buna-S, Polythene.

Explanation

To arrange the polymers Nylon 6,6, Buna-S, and Polyethylene in increasing order of their intermolecular forces, we will analyze each polymer based on the types of intermolecular forces present.

### Step-by-Step Solution:

1. **Identify the Types of Polymers**:
- **Nylon 6,6**: This is a synthetic fiber known for its strength and durability. It exhibits strong intermolecular forces due to hydrogen bonding and dipole-dipole interactions.
- **Buna-S**: This is a type of synthetic rubber (an elastomer) that has weaker intermolecular forces primarily due to van der Waals forces.
- **Polyethylene**: This is a common plastic that has moderate intermolecular forces, which are stronger than those in Buna-S but weaker than those in Nylon 6,6.
