Explain why water and oil don't mix with polar and non polar?

Water is a polar molecule, meaning it has a positive and negative end due to the unequal sharing of electrons. Oil, on the other hand, is made up of non-polar molecules, which have an even distribution of charge. Because of this difference in polarity, water molecules are more attracted to each other than to oil molecules, leading to a separation where the two liquids do not mix. This principle is often summarized by the phrase "like dissolves like," indicating that polar substances dissolve well in polar solvents, while non-polar substances do not.
