Why don’t hexane and hexane dissolve in water?

Water, H2O, is a polar molecule. O is partially negative and hydrogen atoms are partially positive. Hexane has a fairly even charge distribution, which means it is ethereal in nature. Nothing about water and hexane molecules attracts each of them. Therefore, hexane is insoluble in water.

Hexane is a non-polar organic straight long chain compound that has only attractive force, and non-polar solvents also have the same attractive force. Therefore, it helps to solvate the same compounds. But in the polar region, the force of Coulomb attraction prevails, so this organic chain does not easily solvate. Water is a polar solvent and also has a hydrogen bond. This compound cannot be destroyed by hexane molecules, and water molecules cannot bend around hexane molecules.
