Which substance below has the strongest intermolecular forces? A) A₂X, Δ_vapH= 39.6 kJ mol^-1 B) BY₂, Δ_vapH= 26.7 kJ mol^-1 C) C₃X₂, Δ_vapH= 36.4 kJ mol^-1 D) DX₂, Δ_vapH= 23.3 kJ mol^-1 E) EY₃, Δ_vapH= 21.5 kJ mol^-1

Question

Quizplus · Accepted Answer

The enthalpy of vaporization (Δ_vapH) is a measure of the energy required to overcome intermolecular forces and convert a substance from liquid to gas. A higher Δ_vapH indicates stronger intermolecular forces. A₂X has the highest Δ_vapH of 39.6 kJ mol^-1, indicating it has the strongest intermolecular forces among the given substances.
