Question

Arrange the halogens F₂, Cl₂, Br₂, I₂, in order of their
increasing reactivity with alkanes.
(a) I₂ < Br₂ < Cl₂ < F₂ (b) Br₂ < Cl₂ < F₂ < I₂
(c) F₂ < Cl₂ < Br₂ < I₂ (d) Br₂ < I₂ < Cl₂ < F₂

Answer 1

Answer:

Fluorine is the most electronegative halogen and while going down the group electronegativity decreases. The order of electronegativity is F2 > Cl2 > Br2 > I2. As the electronegativity of halogens decreases, their reactivity with alkanes also decreases.

.°. The correct option is (a).
