Write the name of monomers used for getting the following polymers :
(i)Teflon
(ii) Buna-N

Explanation

To answer the question regarding the monomers used for the polymers Teflon and Buna-N, we can follow these steps:

### Step 1: Identify the polymer Teflon
Teflon is a well-known polymer used primarily for its non-stick properties in cookware. It is scientifically known as polytetrafluoroethylene (PTFE).

### Step 2: Determine the monomer for Teflon
The monomer used to produce Teflon is tetrafluoroethylene. The chemical structure of tetrafluoroethylene is represented as:
\[ \text{C}_2\text{F}_4 \]
