Question

Rank the following molecules in decreasing bond energy. Cl₂ Br₂ F₂ I₂ A) I₂ > Br₂ > Cl₂ > F₂ B) Cl₂ > Br₂ > F₂ > I₂ C) I₂ > Cl₂ > Br₂ > F₂ D) Cl₂ > I₂ > F₂ > Br₂

Quizplus · Accepted Answer

Bond energy generally decreases as you move down a group in the periodic table due to increasing atomic size and the corresponding increase in bond length. Therefore, the bond energy of halogens with another atom decreases in the order F > Cl > Br > I, making option B correct.
