Of the following polymers—cellulose, poly(vinyl chloride), nylon, and natural rubber—which one has the weakest intermolecular attraction between its chains?

1. nylon
2. poly(vinyl chloride)
3. cellulose
4. natural rubber

Correct answer: natural rubber

Solution

Natural rubber consists of long, flexible polymer chains with relatively weak van der Waals forces between them, leading to lower intermolecular attraction compared to the more rigid and structured polymers like nylon, cellulose, and poly(vinyl chloride).
