Why oil molecules are not attracted to the water molecules in vinegar?

Oil molecules are nonpolar, meaning they do not have charged regions, while water molecules are polar, having a positive and negative side due to their molecular structure. This difference in polarity leads to a lack of attraction between oil and water molecules. In vinegar, which contains water and acetic acid, the polar water molecules are more attracted to each other than to the nonpolar oil molecules, resulting in the two substances not mixing. Consequently, oil and vinegar tend to separate when combined.
