Why teflon is used for making non-stick coating on cookwares?

Explanation

### Step-by-Step Solution:

1. **Definition of Teflon**: Teflon is a synthetic polymer known for its non-stick properties. Its chemical name is polytetrafluoroethylene (PTFE).

2. **Chemical Structure**: Teflon is made from the polymerization of tetrafluoroethylene (C2F4). The repeating unit in the polymer chain is -CF2-CF2-.

3. **Non-Stick Property**: The unique structure of Teflon gives it its non-stick characteristic. The fluorine atoms in Teflon create a surface that is very smooth and slippery.
