Liquids that are not soluble in each other are called what?

• A. Solubility
• B. Hydration
• C. Miscible
• D. Immiscible

Answer: (D)

Two liquids that do not dissolve in each other are immiscible. This means they form separate layers instead of a single, uniform mixture. The reason Often lies in intermolecular forces: one liquid is polar and can strongly interact with itself (like water via hydrogen bonds), while the other is nonpolar and cannot stabilize those interactions with the polar molecules. When mixed, the energy gained from forming interactions between the two liquids isn’t enough to overcome the existing favorable interactions within each liquid, so they stay separate. Hydration is about water molecules surrounding dissolved particles, not about two liquids mixing. Miscible would describe liquids that do mix in all proportions, so that term doesn’t fit here. Immiscible is the correct description.
