Concept: Solubility is the ability of a compound to be dissolved in a solvent. The solubility of organic compounds are very important in organic reaction and purification. Theory: The solubility of organic compounds is a function of the polarities of both the solvent and the solute (dissolved material).A general rule is  Like dissolves like.. This means if the solute is very polar, a very polar solvent is needed to dissolve it; if it is nonpolar, a nonpolar solvent is needed.he solubility of organic compounds is a function of the polarities of both the solvent and the solute (dissolved material).
