Indicate the order of reactivity of the halogens (F₂,Cl₂,Br₂,I₂)with water (fastest to slowest). A)F₂ > Cl₂ > Br₂ > I₂ B)Cl₂ > Br₂ > I₂ > F₂ C)Br₂ > I₂ > F₂ > Cl₂ D)I₂ > Br₂ > Cl₂ > F₂

Quizplus · Accepted Answer

The order of reactivity of halogens with water is based on their ability to oxidize water to form hypohalous acids, HXO. Fluorine being the most electronegative, has the highest oxidizing power, followed by chlorine, bromine, and iodine. Hence, the correct order of reactivity is F₂ > Cl₂ > Br₂ > I₂.
