Basically, polar solvents dissolve polar substances, and non-polar solvents dissolve non-polar substances. Water is polar, oil is non-polar.
No, non-polar molecules do not dissolve in water. Remember, like substances dissolve like substances (like dissolves like). Water is POLAR; therefore, non-polar molecules will not dissolve in it. Non-polar molecules dissolve in non-polar solutions.
It does not dissolve in water as it is non-polar. Remember non polar solvents dissolve non polar solvents and polar solvents dissolve polar solvents. Since Cyclohexane is non polar and water is polar they will not dissolve each other, instead two inseparable layers of liquids are formed.
Because it is non-polar itself.Remember the addage : Like Dissolves Like.Polar solvents dissolve polar solutes. And non-polar solvents dissolve non-polar solutes.
Lipids dissolve in any non polar solvent (Because it is non polar it can't dissolve in water)
Because they're non-polar,and non-polar substances don't dissolve in water,they dissolve in petroleum,or other non-polar solvents.
No, sucrose is polar while hexane is non-polar. Polar solutes dissolve in polar solvents while non-polar solutes dissolve in non-polar solvents.
No,as it is a rule of thumb that likes dissolves like,which means that polar will dissolve in polar and non polar in non polar.There are a few exceptions. Water, a polar substance, can dissolve some very small non-polar substances, such as oxygen.
If it does not dissolve in water then it's non polar, if it does then it means it's polar. (Ex. Butter does not dissolve in water, there for butter is a non polar) If butter dissolve's in cooking oil then cooking oil is non polar.
Hexane is a non-polar solvent, so it will not dissolve in water. Kerosene is non-polar so it will dissolve in Hexane.
