A
A mixture of two nonpolar gases
B
A solid composed of only covalent molecules
C
A pure sample of a nonpolar molecular compound
D
A solution containing an ionic compound dissolved in a polar solvent
Verified step by step guidance1
Understand that ion-dipole intermolecular forces occur between ions and polar molecules. These forces are significant when an ionic compound is dissolved in a polar solvent.
Recall that ionic compounds consist of positively and negatively charged ions, while polar molecules have a permanent dipole moment due to uneven distribution of electrons.
Recognize that in a solution where an ionic compound dissolves in a polar solvent (like NaCl in water), the positive and negative ions interact with the partial charges on the polar solvent molecules, creating ion-dipole forces.
Contrast this with mixtures of nonpolar gases or pure nonpolar molecular compounds, where ion-dipole forces do not occur because there are no ions or permanent dipoles present.
Conclude that ion-dipole forces are typically exhibited in solutions containing ionic compounds dissolved in polar solvents, making this the correct scenario for such intermolecular interactions.
