Give an example of oxidation of halide by another halogen. Explain the feasibility of the reaction.

Explanation

### Step-by-Step Solution

1. **Identify the Halogens**: The halogens include fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). Among these, fluorine is the strongest oxidizing agent, followed by chlorine, bromine, and iodine.

2. **Example of Oxidation**: A classic example of oxidation of a halide by another halogen is the reaction between chlorine (Cl₂) and potassium iodide (KI). The reaction can be represented as:
\[ \text{Cl}_2 + 2 \text{KI} \rightarrow 2 \text{KCl} + \text{I}_2 \]
