Transcribed Image Text: Amongst the following compounds, identify which are insoluble, partially soluble and highly soluble in water? In the organic laboratory, reactions are often run in nonpolar or slightly polar solvents such as toluene (methylbenzene), hexane, dichloromethane, or diethylether. By using the solubility guidelines in Table 5.1, determine whether the positive ions from one compound combine with the negative ions of the other to form soluble or insoluble compounds. 1. C. HF The result is that the alcohol is able to form more energetically favorable interactions with the solvent compared to the ether, and the alcohol is therefore more soluble. Thus, water dissolves many ionic compounds because it is "like" them. To conduct electricity, a substance must contain freely mobile, charged species. Soluble and transparent Te-diol compounds would be a good choice. Water and other polar molecules are characterized by a slightly positive region and a slightly negative region and are therefore attracted to ions, as shown in Figure \(\PageIndex{2}\). The reduction of the electrostatic attraction permits the independent motion of each hydrated ion in a dilute solution, resulting in an increase in the disorder of the system as the ions change from their fixed and ordered positions in the crystal to mobile and much more disordered states in solution. lil_t808.

It is able to bond to itself very well through nonpolar van der Waals interactions, but it is not able to form significant attractive interactions with the very polar solvent molecules. B) CH3CH2OH & H2O Previously, we investigated the possibility of using opal-cristobalite rocks for fine purification of water from highly soluble organic compounds [1, 2]. Because the outside of the micelle is charged and hydrophilic, the structure as a whole is soluble in water. When you try butanol, however, you begin to notice that, as you add more and more to the water, it starts to form its own layer on top of the water. As an example, it was shown that the diatomite from the Inzenskoe deposit in Interactive 3D images of a fatty acid soap molecule and a soap micelle (Edutopics).
