Detailed Solution

Reactivity of halogens decreases with decrease in their electronegativity. Halogenation reaction of alkanes follows the radial mechanism. On moving from F₂ to I₂, energy releases from the propagating step decreases which means that proves the reactivity order.

$F_{2} > {Cl}_{2} > {Br}_{2} > I_{2}$
