Predict whether the boiling points of F₂, Cl₂ and Br₂, are arranged in increasing or decreasing order. Justify your answer.

• A. They are arranged in order of increasing boiling point because they are arranged in order of increasing mass.
• B. They are arranged in order of decreasing boiling point because they are arranged in order of increasing mass.
• C. They are arranged in order of increasing boiling point because they have different intermolecular forces which are arranged in order of increasing strength.
• D. They are arranged in order of decreasing boiling point because they have different intermolecular forces which are arranged in order of increasing strength.
