In the presence of peroxide, hydrogen chloride and hydrogen fluoride do not undergo anti-Markovnikov's
addition reaction with alkenes because-
1. Both are highly ionic
2. One is oxidizing and the other is reducing
3. One of the steps is endothermic in both the cases
4. All the steps are exothermic in both cases
