Multiple Choice

How does the polarity of two liquids affect their miscibility?

Liquids with similar polarity are generally miscible with each other.

Nonpolar liquids are only miscible with polar liquids.

Polarity has no effect on the miscibility of liquids.

Liquids with different polarities are always miscible.

Verified step by step guidance

Understand the concept of polarity: Polarity in molecules arises from differences in electronegativity between atoms, leading to partial positive and negative charges within the molecule.

Recognize that miscibility refers to the ability of two liquids to mix and form a homogeneous solution without separating into two phases.

Recall the principle 'like dissolves like,' which means that substances with similar polarity tend to be miscible because their intermolecular forces are compatible.

Analyze the interaction between polar and nonpolar liquids: Polar liquids have dipole-dipole interactions and hydrogen bonding, while nonpolar liquids mainly have London dispersion forces, making them generally immiscible with each other.

Conclude that liquids with similar polarity are generally miscible, while liquids with very different polarities tend to be immiscible, which explains why polarity affects miscibility.
