Why iodination of alkanes is carried out in the presence of oxidizing agents?

Explanation

### Step-by-Step Solution:

1. **Understanding Iodination of Alkanes**:
- Iodination is a substitution reaction where iodine is introduced into an alkane. This reaction is typically slow and can be reversible.

2. **Formation of HI**:
- During the iodination of alkanes, hydrogen iodide (HI) is produced as a byproduct. For example, when methane (CH₄) undergoes iodination, it can form methyl iodide (CH₃I) and HI.
