Examples of Immiscible LiquidsOil and Water - These two liquids do not mix because oil is non-polar while water is polar. Their different molecular structures prevent them from dissolving in each other.Oil and Vinegar - Often seen in salad dressings, oil and vinegar separate into two layers because oil is hydrophobic (doesn't mix with water-based vinegar).Mercury and Water - Mercury is a metal in liquid form and does not mix with water due to differences in polarity and density.Hexane and Water - Hexane is a non-polar solvent and water is polar, so they do not mix and form separate layers.In all these cases, immiscible liquids don’t form a uniform solution because their molecules are too different in nature to blend together.
