Why does the addition of \(\text{HI}\) in the presence of a peroxide catalyst not follow anti-Markovnikov's rule?
| 1. | \(HI\) is a strong reducing agent. |
| 2. | The \(\text{H–I}\) bond is too strong to be broken homolytically. |
| 3. | The \(I\) atom combines with \(H\) atom to give back \(HI.\) |
| 4. | The iodine atom is not reactive enough to add across a double bond. |
