WebSolubility and miscibility describe similar phenomena, but they are not the same. Solubility exists on a spectrum. Substances may combine together poorly or very well, and it's possible to describe solutions as "partially soluble" or "mostly soluble." Miscibility, however, is an absolute property that is not expressed in degrees.

WebIn this example diethyl ether is split into ethanol and iodoethane: The reaction is regioselective , as iodide tends to attack the less sterically hindered ether carbon.
