Match the non-covalent interaction with an example of a molecule pair that the non-covalent interaction acts between.
-London dispersion

Question

Quizplus · Accepted Answer

London dispersion forces act between all molecules, but are particularly significant between non-polar molecules or molecules with very small dipoles. C₂H₆ and C₄H₁₀ are both non-polar molecules, so they would experience significant London dispersion forces. CHCl₃ and CH₃OH have small dipoles, but the difference in electronegativity between carbon and hydrogen is small enough that the dipoles are not significant, so London dispersion forces would be the strongest interaction between them. Na⁺ and H₂O would not experience London dispersion forces, as they are both polar molecules with significant dipoles. Similarly, CH₃OH and H₂O have significant dipoles and would experience stronger dipole-dipole interactions than London dispersion forces.
