Question

Why organic substances (non polar)are soluble in organic (non polar) solvents?

Answer 1

The polar solvent interacts with itself with strong bonds, lowering the total energy of the system. The nonpolar molecules interact with weak bonds. If you put them together, it is not favourable to get them into one phase - nonpolar molecules would get in the way of the polar ones, breaking the interactions between them, thus raising the total energy substantially - that is not favourable at all. So in this case, the system would make two phases. But if the organic is polar enough - like acetic acid or formaldehyde, the bonds between them and for example water will be so strong, that they'll be miscible in all ratios.

Answer 2

Any substance dissolves in other because it is able to break the bonds between constituent elements / molecules of the solvent and form weak bonds.

For an organic substance to dissolve in an ionic solution, its covalent constituents should be strong enough to break the ionic bonds. That implies, a bond should be formed between covalent element of the organic particles and the ionic solvent.

This is highly unlikely. That's why most organic compounds are soluble only in organic solvents.

Water is a good solvent for a few organic solvents, but that mainly is due to formation of Hydrogen bonds.
