Arrange the following polymers in increasing order of intermolecular forces. Also calssify them as addition and condensation polymers :
Nylon - 6, neoprene, PVC.

Explanation

To solve the problem of arranging the polymers Nylon-6, Neoprene, and PVC in increasing order of intermolecular forces and classifying them as addition or condensation polymers, we can follow these steps:

### Step 1: Understand the Structures of the Polymers
- **Nylon-6**: It is a condensation polymer formed from hexamethylenediamine and adipic acid. It has amide linkages (-CONH-) which contribute to strong hydrogen bonding between chains.
- **PVC (Polyvinyl Chloride)**: This is an addition polymer formed from the polymerization of vinyl chloride. It has polar C-Cl bonds, which can lead to dipole-dipole interactions.
- **Neoprene**: This is also an addition polymer made from the polymerization of chloroprene. It has a structure that allows for some degree of intermolecular forces but is less polar than Nylon-6.

### Step 2: Analyze the Intermolecular Forces
