How are immiscible liquids best described?

Immiscible liquids are best described as one liquid floating on the other because they do not mix at a molecular level. This phenomenon occurs because the molecular properties of the liquids differ significantly, such as their polarity. For example, when oil and water are combined, the oil, being less dense, will float on top of the water. This separation occurs because the molecules of immiscible liquids are not compatible, resulting in distinct layers rather than a homogenous mixture.

While it may seem that one liquid "repels" the other, the primary characteristic of immiscible liquids is their tendency to stratify into distinct layers rather than interact at their surfaces. Other terms like "entrained solution" or "mixing well together" suggest a degree of interaction and blending that simply does not apply to immiscible substances.
