GENERAL KNOWLEDGE

Detailed explanation-1: -Liquid water is held together by hydrogen bonds. (Liquid water has fewer hydrogen bonds than ice.) Oils and fats not have any polar part and so for them to dissolve in water they would have to break some of water s hydrogen bonds. Water will not do this so the oil is forced to stay separate from the water.

Detailed explanation-2: -In fact, oils are hydrophobic, or “water fearing.” Instead of being attracted to water molecules, oil molecules are repelled by them.

Detailed explanation-3: -Oil molecules, however, are non-polar, and they can’t form hydrogen bonds. If you put oil and water in a container, the water molecules will bunch up together and the oil molecules will bunch up together, forming two distinct layers.

Detailed explanation-4: -Oil doesn’t dissolve in water, i.e., it is immiscible in water. This is because its molecules are non-polar while water is a polar solvent. Non-polar substances do not dissolve in polar solvents and vice-versa.

Detailed explanation-5: -The structure of an oil molecule is non polar. Its charge is evenly balanced rather than having one positive and one negative end. This means oil molecules are more attracted to other oil molecules than water molecules, and water molecules are more attracted to each other than oil, so the two never mix.
