The correct Answer is:
To arrange the halogens \( F_2, Cl_2, Br_2, I_2 \) in order of their increasing reactivity with alkanes, we need to consider the nature of the halogens and their reactivity patterns. ### Step-by-Step Solution: 1. **Understanding Reactivity with Alkanes**: - Alkanes are generally unreactive due to their stable C-H bonds. However, they can react with halogens under certain conditions, typically in the presence of UV light or heat, leading to halogenation. 2. **Reactivity of Halogens**: - The reactivity of halogens with alkanes decreases as we move down the group in the periodic table. This is because: - Fluorine (\( F_2 \)) is the most reactive halogen due to its high electronegativity and small size, which allows it to form strong bonds with carbon. - Chlorine (\( Cl_2 \)) is less reactive than fluorine but still reacts vigorously with alkanes. - Bromine (\( Br_2 \)) is even less reactive than chlorine. - Iodine (\( I_2 \)) is the least reactive halogen with alkanes due to its larger size and lower electronegativity. 3. **Order of Reactivity**: - Based on the above reasoning, we can arrange the halogens in order of increasing reactivity with alkanes: \[ I_2 < Br_2 < Cl_2 < F_2 \] ### Final Answer: The order of increasing reactivity of halogens with alkanes is: \[ I_2 < Br_2 < Cl_2 < F_2 \]
