CH₂F₂ has a dipole moment of 1.93 D and a boiling point of -52 $\circ$ C. CH₂Cl₂ has a dipole moment of 1.60 D and a boiling point of 40 $\circ$ C. The boiling point of dichloromethane is higher than that of difluoromethane because of ________ A)dispersion forces. B)dipole-dipole forces. C)ion-ion forces. D)ion-dipole forces. E)hydrogen-bonding forces.

Question

Quizplus · Accepted Answer

Dichloromethane (CH₂Cl₂) has a higher boiling point than difluoromethane (CH₂F₂) primarily due to stronger dispersion forces, which are more significant in molecules with larger, more polarizable atoms like chlorine compared to fluorine.
