Why does oil not dissolve well in water?
Answer and explanation
Correct answer: Their nature is different
Water is polar, whereas most oils are largely non-polar. Polar water molecules do not form sufficiently favourable interactions with non-polar oil molecules, so the two liquids separate. This illustrates “like dissolves like,” making A correct. Oil is not always solid, and colour or ordinary pressure is not the main reason.
