Like dissolves like

[Isabelle Fontanilla 1I]

Based on the rule: like dissolves like, I know that polar solvent dissolves polar compounds. However, I do not know how non-polar solvent dissolves non-polar compounds. Can someone explain? Is it because of London Dispersion Forces? If so, won't non-polar solvent still be able to dissolve polar compounds(if there is enough energy)?

Non polar solutes dissolve in non polar solvents, due to London Dispersion Forces. The reason as to why non polar solutes won't dissolve in polar solvents is that the London Dispersion forces in non polar molecules are much weaker in comparison to to the polar attractions between the permanent dipoles in the polar molecules that make up the solvent.

nonpolar compounds have a tendency to aggregate together...such is the case in a cell's lipid bilayer, where the nonpolar, hydrophobic tails face inwards towards another while the hydrophilic, polar heads face outwards. This is key towards regulating a cell's metabolism.

I'm sorry this is bit out of topic but what part of the book is this? will test 3 cover this too??
