Rank these in order of increasing boiling point: F₂, HF, HCl.
A.F₂ < HCl < HF
B.HF < HCl < F₂
C.F₂ < HF < HCl
D.HCl < F₂ < HF
Explanation
Core Concept
F₂ relies on weak dispersion forces alone. HCl adds dipole–dipole forces. HF adds hydrogen bonding — the strongest of the three — so HF boils highest despite its small molar mass.
Correct Answer
AF₂ < HCl < HF
